How can I prevent my e-mails getting marked as spam?

You have your own e-mail server, but your e-mails are landing in the spam folder or do not even arrive? This can have several reasons. This tutorial will show you the most important tricks and often overseen configuration mistakes. If you have a webspace package, you will only need the point SPF of this tutorial. In this tutorial we will often use the fictional domain mail.yourdomain.com and the IP address 1.2.3.4. Please replace them with your own ones when you are doing the tests or configuration.

SMTP banner

The SMTP banner is the label of your e-mail server. When it connects to a different e-mail server, it is introducing itself with it. If you have a server from us, it will, at the beginning, answer with something like this:

m1234.contabo.net

A lot of e-mail providers will not accept such a label and send your e-mail directly into the spam folder. So it is better to choose a less generic one like:

mail.yourdomain.com

Please notice, that is has to  be a fully qualified domain name ( FQDN) . That means there has to stand a subdomain like "mail" in front of yourdomain.com. You can request the current SMTP banner by connecting to your server with Telnet over port 25. You can do this in Windows by entering the following command into the Windows  command prompt:

telnet 1.2.3.4 25

Please use your own server IP here. If you are using Windows, you will have to activate Telnet first! (Start --> Control Panel --> Programs and Features --> Turn Windows features on or off--> wait a moment, then check the Telnet Client check box and finish with clicking on OK)
The output might look like this:

220 m1234.contabo.net ESMTP Postfix (Debian/GNU)

"m1234.contabo.net" is the important information in this line. You can leave the session by entering "quit" and hitting enter. In cPanel and Plesk, the mailserver's name in the SMTP banner is equal to the hostname. So you can alter it by changing the hostname in the administration panel.
If you are using Plesk on a Windows server, it is not so easy to change the banner. Please log into your server over RDP, open the tool "MailEnable" and go to: MailEnable Management --> Servers --> localhost --> Connectors. Then choose in the opening list SMTP, click on it with you right mouse key and open "Properties". In the opening window, there are four fields you have to fill in:

Local Domain Name

Here you have to enter you main domain. For example: yourdomain.com.

Default mail domain name

This is your e-mail server name in the SMTP banner. For example: mail.yourdomain.com

DNS Addresses

Here you have to enter the DNS servers. If you have your server in one of our datacenters, the following addresses would work perfectly:

for Nuremberg:
213.136.95.10 213.136.95.11

for Munich:
79.143.183.251 79.143.183.252

Notification email address

Please enter an existing e-mail address.

If you are using Postfix instead of an administration panel, you can change the SMTP banner by using this command in the terminal:

postconf -e "myhostname = mail.yourdomain.com" && postfix reload

Please replace "mail.yourdomain.com" with the new domain name of the e-mail server.

PTR

The PTR, or also called reverse DNS record, is the counterpart of the A-record in a DNS zone.

A-record:

mail.yourdomain.com --> 1.2.3.4

PTR:

1.2.3.4 --> mail.yourdomain.com

Most e-mail servers only accept an e-mail, if the PTR is exactly the same as the name of the mailserver in the SMTP-Banner! If you have for example the following SMTP-Banner:

220 mail.yourdomain.com  ESMTP Postfix (Debian/GNU)

You have to change your PTR like in the upper example, what can be done easily in the Customer Control Panel. Please notice, that you have to change the PTR of the IPv6 address too, if you are using IPv6 additionally to IPv4. It will not harm to do it anyway, if you are not sure.

SPF

With the SPF record you determine that it is only allowed to send e-mails from specific IP addresses. Many e-mail servers are considering e-mails from domains without SPF record as spam. You can add an SPF record in the Customer Control Panel with the DNS Zone Management. The following one should work in most cases:

86400 in TXT "v=spf1 +a +mx ~all"

It will allow the IP named in the A-record and the one of the mailserver, named in the MX-record.

If you use one of our webspace packages, please use the following one:

86400 in TXT "v=spf1 +a +mx +a:mail-relay.contabo.net ~all"

If you have a special configuration, you can use a tool like this to generate an individual SPF:

SPF-Wizard

Blacklists

We always do test our IP addresses, before we give them to our customers. But it is not impossible, that your IP is currently on a blacklist. This will cause your sending attempts to fail despite all your tries to achieve a perfect configuration. If you assume that your IP might be on such a list, you can test for the most important ones on this site:

MX-Toolbox Blacklist Check

Please enter the IP address of your server and wait some seconds for the test! If the IP is listed somewhere (marked in red), you should contact the owners of this list. They will offer a removal form on their home page. The IP should be removed in a few days. Some e-mail providers have their own lists, that can not be reviewed so easily. They normally will send you a bounce e-mail to signal, that the sending attempt failed, with the reason included in it. If they mention an internal blacklist, you can find below some links to the removal forms of such providers:

Microsoft
Yahoo
Google

If you have problems getting your IP removed from such a list, please write an e-mail with the error message and the IP to support@contabo.com. We will help you solving this problem.

Additional points

If you have paid attention to all the points so far, and your e-mails have still problems with reaching the recipient or are landing in the spam folder, it is time to look for the reason in close detail. Have you got a reply when the e-mail was not accepted? Read this e-mail carefully. Often there stands the reason for this behaviour! If you have found such a message, but it does not help you, you are free to sent it with the complete header to our support. Our team of experts at support@contabo.com has a lot of experience with solving such problems!

If the e-mail is arriving but landing in spam, the header of the received e-mail will often contain useful hints. Especially Google makes it easy for the owners of small e-mail servers and often adds a link to its e-mail guidelines. Therefore, it might be useful to send a test e-mail to a Gmail address too, for a further analysis!

Please also take a look on the free MX-Toolbox SMTP Check. Here you have to enter the domain of your e-mail address. The site will test your configuration for common problems!

If nothing helped

If you have worked through the whole tutorial, and there are still problems with sending e-mails, or you need help at some point, you can contact our support. We are there for you everyday from 8:00 to 23:00 (German time) at support@contabo.com.

Mounting of additional hard drives in Windows

In this tutorial, we are going to mount an additional hard drive in Windows. As you may notice, we will do so in Windows Server 2012, but the procedure is basically the same with Windows Server 2008.

At first, we need to open a menu by right-clicking the Start button:

_2015-05-28_18-14-12

We must select Disk Management to open the Disk Management service. If Windows identifies a new hard drive, a pop-up menu opens:

mbrgpt

For volumes smaller than 2 TB, we choose MBR, for larger disks, we select GPT. As the hard drive in our example only has a capacity of 100 GB, we'll go with MBR here. By clicking OK, the chosen partition table will be written to the hard disk. After that procedure, we will be sent to the main menu of the Disk Management service. Alternatively, one can reach this overview via Control Panel => Computer Management.

haupt

As we can see here, our new hard drive is listed as Disk 1. But before we can use it for storing data, we need to partition and format it. Therefore, we right-click the rectangle next to the box which says Disk 1 and choose New Simple Volume.

haupt2

A wizard opens. It is quite self-explanatory and you can't do anything wrong by using the pre-selected and suggested values. Per default, the wizard uses the whole disk capacity for the new partition and formats it with the file system NTFS, which is recommended for Windows. Of course, you are free to change those settings, but in our example, we go along with them.

ntfs

The name of our new partition is STORAGE, but of course you can name it as you wish.

Once you went through the wizard, the new hard drive will be ready to use. It will also be visible in the Explorer:

10 years Contabo in pictures: Part 2

In our last blog post we have already given you an overview about the history of Contabo since its foundation.

Now we would like to move on into 2006. For a better understanding keep again an eye on the chronicle of Contabo:

Contabo through the ages

In March 2006 we opened our first office in the heart of Munich. During a long night session we set up several tables, chairs and computers in our new office which was located in a mixed building with offices and apartments. That’s why it wasn’t really surprising (but for us it somehow was at this moment) when an angry neighbor complained about our noisy furniture assembly and installation.
So we finished our hammering, drilling and screwing at 3 o’clock in the morning and continued on the next day.
Thanks to our apology and a bottle of red wine the domestic peace could be restored again.

According to our former company size our first office was very small and contemplative. Nevertheless, nothing was missing.
Right from the beginning a “Coke”-refrigerator of the brand “Bosch” in 50s retro style had been ordered and has been providing us with refreshments until today. By the way, the purchase price was 700 Euros plus delivery expenses.

 

Impressions from 2006 of our first office:

 

office1_small

office1coke_small

office1couch_small

Unfortunately, we didn’t stay in the office for a long time although we had been blessed with a delicious food infrastructure like Mc Donald’s, Pizza Hut and several Döner restaurants because of its location in the middle of the city center.
We took advantage of the possibility to use a small data center in the middle of Munich operated by the carrier Tiscali with exclusive access to our servers.  Tiscali itself stopped all its business in Germany at this time because they didn’t perform profitably any more. Further details of the Italian telecommunications company which was our partner at that time can be found on Wikipedia.
In 2007 we split all of our servers in two different locations; one was located in Frankfurt and one in Munich. At the same time we moved our office to the former office rooms of Tiscali to operate near our servers. This gave us the possibility, in the event of any server problems, to react instantly at any time.
This relocation was the kick off of our colocation and housing product offers.
From this time, customers had the possibility to colocate their own server hardware in our data center and to benefit from a very fast internet connection, from excellent international routing, redundant air-conditioning and power supply. The number of servers increased rapidly.

 

Impressions from 2007 of the data center in Munich:

The racks of Rittal shown on the pictures above have been taken over from Tiscali by us later on and are still in use in our data center.

 

Impressions of our 2nd office at Tiscali:

We left the building in 2009 when we opened our today’s office and data center in Giesing/ Munich.

10 years Contabo in pictures: Part 1

A few days ago Katharina gave you a detailed overview about the history of Contabo in her blog post “Contabo through the ages! The story so far…”.
Based on the mentioned most important milestones of the past 10 years we are going to publish now and within the next few days some pictures, photos and texts which we have been collecting during the last years.

Let’s have a look again on the chronicle posted by Katharina…
Contabo through the ages

…and let’s go back to the very beginning when we put our first own rack server into operation at our first data center location in “Mainhattan”, in Frankfurt am Main, Germany.

In 2004 the first machines went online in the commonly known “Redbus Interhouse” at Lyoner Straße 28. At the beginning we just started with a space for 10 (or 15?) servers, but soon, our company had been growing fast, and thus, also the number of servers in our data center.
Not only we have been delighted about our rapid growth, but also our IT service provider who has been responsible for the handling of our hardware on site and who we worked with for more than 4 years, until we left Frankfurt am Main a little bit later.
Within a few months our server farm grew from 10 servers to 100 servers, and until today our business is expanding at an ever-increasing rate.

A few months later our long-term IT service provider decided to open another data center location a few houses away from us in Lyoner Straße 15. It was probably not only our very positive development which was responsible for their new data center, but we certainly have made an important contribution to that. At this time Giga-Hosting/ Contabo occupied the highest numbers of servers in their data center.
Today, 10 years later, the Tier1 carrier and global player “Cogent” has settled down right there, in the same datacenter we had used for many years at that time, with his German headquarter.

In the following you will find some impressions of our time (2004-2008) in Frankfurt am Main:

rackserver_small

rack_small

server2_small

server_small

rz_small

cam_small

Our objective has always been to stay responsible for all of our servers. This means, we have chosen all single items and the infrastructure of our servers on our own and ,according to our ideas, we created server systems which were ready-to-use. We worked day and night to deliver our servers to Frankfurt am Main as soon as possible. And believe me, this was really hard work.

The following picture shows our already packaged servers shortly before its transportation to Frankfurt. According to the file attributes the picture was taken in October 2005 at 2:00 AM in the morning.

Picture006_small

Giga-Hosting staff often travelled to Frankfurt to support the technicians there. I can warmly recommend “Motel 1” as accommodation because that’s where the team stayed during our visit and it was pretty nice.
It was situated between the airport and the data center and that’s why we haven’t seen a lot of the city during our stay.

This was the view out of our hotel room - we had to be content with a view towards another hotel instead of impressive pictures of the city centre and the famous Frankfurt skyline:

motel_small motel2_small

While we have been focused on the hardware and on the infrastructure of our servers, we took care of one of our most important matters: our product range.
When we started planning our company we agreed on three basic principles which focused on our customers and that have been applied consistently and uncompromisingly to this very day:

1) Discount prices
2) Instant service
3) The customer is king

According to these principles we operated day by day.
We were working hard to continually improve our products like webspace, servers, colocation, domains and its sustainable development. From time to time we offered radical price reductions but always together with high quality products and support.
This concept has been proven for years and it is still our company philosophy.

In the following you will find some impressions of some former marketing promotions and offers:

In March 2006 we opened the first office in Munich for our 1st and 2nd level support department. Since that time our team has been growing constantly.

High demand for our VPS and Dedicated Servers!

Short after our company name change we reduced the prices of our dedicated and virtual servers and some of our upgrades.
Since last week our high-end server “Dedicated Server X”, which includes a powerful Intel Core i7 3930K processor, 64 GB DDR3-RAM and 256 GB SSD with 6 Gbit/s + 3 TB HDD, can already be ordered at the ridiculously low cost of 109.99 EUR/ month.
Have a look on our server overview at http://contabo.com/?show=servers – our prices of all other servers are quite reasonable as well.

Furthermore, we doubled the performance of our Virtual Private Servers (VPS). From now on, our customers get 16 GB RAM for only 29.99 EUR/ month. These 16 GB RAM are guaranteed to be available, contrary to other offers. You get 100% performance in full!
In addition to that the virtual machine offers 800 GB HDD and 4 cores with 3,2 Ghz each. All together for just 29.99 EUR/ month is a more than excellent cost-benefit ratio, in our opinion.

The consequences of the price reduction are not really very surprising for us but very pleasing. Every day our support team, that is responsible for new customers and for the setup of all ordered hosting products, is doing a great job by providing almost instant setup, usually within a few hours after receipt of payment.

When we checked our new orders today at 10.30 in the morning we already recorded new orders of
- 30 VPS and
- 4 Dedicated Servers.
We are already excited what count we are going to reach at the end of the day ;-).

Parallel to all the new orders the volume of support requests increases. Reasons for that are not because of errors or malfunctions of our server hardware – most of the support enquiries contain individual requests, technical issues and the startup procedure of the servers by the customers.
Even in times when more assistance is required by our customers we are taking care of every phone and email enquiry instantly, often only within a few minutes.
In short: Contabo is able to provide competent instant service and also care for individual requirements someone may have. The office is occupied from 8 am to 11 pm on 365 days a year including holidays and weekends.

We would like to take this opportunity to say thank you to all our new and existing customers. Thank you for having placed your trust in us! We promise to keep on working hard to provide optimum service in combination with an excellent price performance ratio.
For further questions or a detailed product advice feel free to contact our support team (support@contabo.com). We are looking forward to your request.
