<p>Kostja:</p>
|
||
<p>I have been using the workaround.org ISPMAIL tutorials for many years and still do it every time I upgrade my
|
||
mailserver. It is a neat and straightforward approach and saves me a lot of time I otherwise would have to spend
|
||
reading manuals, finding new packages and trying things out. Everything is on the point and I get the information I
|
||
need, that’s perfect. Thank you very much for you great work.</p>

|
||
<p>David:</p>
|
||
<p>I just finished setting up my ~fifth ispmail server (squeeze, 2x stretch, now bullseye) and this time I didn’t even
|
||
bother to do the recommended checks after each step because I knew that after following (and unterstanding) your
|
||
tutorial, the server would go like a Swiss watch. I wasn’t disappointed. Everything works and again I learned a lot.
|
||
Thank you for putting that much effort into the tutorials!</p>
|

|
||
<p>Yannis:</p>
|
||
<p>Just wanted to say thanks for your amazing work. Not only proved up to date and accurate technically, but it is also
|
||
presented in a very educational way. It really is high-quality learning material.</p>

|
||
<p>Ezerotszaz:</p>
|
||
<p>I’m finally done setting up two of these mail servers – for myself and also for a friend. I struggled a lot when I was
|
||
doing it for the first time, but after days of work it is done, it is working properly, I can send(and receive..) from
|
||
four different addresses and I could not be happier! Thank you so much for the insane amount of work that you put into
|
||
this awesome guide.</p>
|
||
</li>
|
||
<li>
|
||
<p>Impli:</p>
|
||
<p>It had been a long time since I had installed a mail server and the few tutorials I could find were not explicit. But
|
||
your guide is very well done. Complete and very detailed. With even some technical information as a bonus for the
|
||
curious.</p>
|
||
</li>
|

<li>
|
||
<p>Niko:</p>
|
||
<p>I really like this guide. I was able to learn some new stuff and setup a nice configured server. I now have a server
|
||
running 2 domains and several user accounts. It took me a few evenings of my spare time and i think it was worth it.
|
||
Thank you very much for your guidance!</p>

|
||
<p>Michael:</p>
|
||
<p>Great guide! Thanks! Very structured and clear! It took me about 2 hours to have a fully funktional email server
|
||
including ISPmail on a Raspberry Pi 3 Model B Rev 1.2 with Raspbian GNU/Linux 11.</p>
|
||
</li>
|
||
<li>
|
||
<p>David:</p>
|
||
<p>Thank you so very much Christoph. I now have a successful mail server running on Linode, and it has all the pieces you
|
||
have detailed here. It works very well. Best of all, I understand how the pieces hang together.</p>
|
||
</li>
|
||
<li>
|
||
<p>Shukuru:</p>
|
||
<p>This guide is pure gold. As a professional developer with some sysadmin skills I was able to set up my first email
|
||
server in a week. I learn a lot about how emails works and I can now take control on my privacy. Thanks.</p>

<li>
|
||
<p>Panos:</p>
|
||
<p>I am proud to be able to thank the author of this series of Guides publicly, for all the unbelievable work he has
|
||
done, all these years. To anyone wishing to truly understand what running a mail server is about, this is the proper
|
||
place to be.</p>

<p>Cody:</p>
|

<p>Seen this guide a few times before and found it to be the most comprehensive one available.</p>

<li>
|
||
<p>Anthony:</p>
|
||
<p>Thanks again for such a comprehensive guide. I’ve been using it for several years and I appreciate the updates for the
|
||
new versions. I just did a “speed run” on a test mail server/domain and it took about 2 hours. TLS/DKIM/SPF are all
|
||
passing too! I’ve gotten a lot of practice with your guide over the last few versions, so I would hope that I can
|
||
complete it quickly.</p>
|
||
</li>
|
||
<li>
|
||
<p>James:</p>
|
||
<p>Thanks Christoph, For your work running this site and the ISPmail guides. I’ve been following them for each Debian
|
||
release since Wheezy. I use my mail server primarily for my personal email address and also have a handful of friends
|
||
using it. Works great.</p>
|
||
</li>
|
||
<li>
|
||
<p>Robbert:</p>
|
||
<p>I have been using this guide for 10 years now with great success. I truly appreciate how you explain each step you do.
|
||
This makes it very easy to follow, and also easy to deviate from the guide if desired. Thanks a lot.</p>

|
||
<p>Nicole:</p>
|
||
<p>I used this guide already with my first mail servers I set up 15 years ago (round about, I’m not quite sure). It
|
||
always worked fine and is a very big help! I have Debian servers with 5 – 30 users only, including one community
|
||
project where also newsletters (i.e. many mails) are sent. Today I set up my newest mail server and all works fine. I
|
||
want to thank Christoph for his great work and support and hope the guide will never end 🙂</p>

|

<p>Thank you Christoph. I’ve just setup my mail server and i’m very happy with it. I’ve learned a lot.</p>
