Success stories

I would appreciate if you leave a comment here telling others if your mail server is running. Perhaps even a word about the purpose of the mail server and the number of users you have. That allows others to see that their time is well-spent and indeed leads to a working mail server. Thanks for your feedback.

    A huge thank-you to you Christoph. I’ve spun down my old mail server, and everything is working splendidly on this new build. It’s just a small operation with 6 domains and a handful of users, but working well all the same.

      Yay, thanks for your feedback. That makes at least two of us who made it. 🙂

    I’m not fully through, but I have used some older guide to set my mailserver up and it did work just fine. I did not follow the instructions exactly, because I did not set up a new server with Debian 10 and instead used what I migrated from and left some settings as they were. But at the moment my mailserver does work again and has a neat new spamfilter (replaced the spamassasin). I will look at the rest of the tutorial at a later time.
    If I’m honest: I don’t know why I even use that overkill of a mailserver. It runs on a server at home and I’m the only user and nobody ever sends me mail there, because nobody knows the address. But I use it to get status mails from my server (cron jobs, updates, etc.). Not really needed, but I do it for the fun of it. I plan to try D-Push or Z-Push to get mails pushed onto my mobile, next.

      Just FYI if you want to add that to your tutorial anytime. Push-Mail with D-Push works realtively easy. I had to apt install d-push (which installed z-push and everything and even enabled the configurations in the webserver).

      I had to add some paths to the php_admin_value open_basedir in my apache configuration. The paths I had to add were /usr/share/z-push/:/etc/share/z-push/:/var/log/z-push/:/var/lib/z-push/
      After that some configurations are required in /etc/z-push. You can add the correct timezone in z-push-conf.php in the define ‘TIMEZONE’. And in the same time I had to set the Define ‘BACKEND_PROVIDER’ to ‘BackendIMAP’.

      After that some configuration in the imap.conf.php is required. Mainly the server data. I had to change the IMAP_PORT to 993 and the IMAP_OPTIONS to ‘/ssl/novalidate-cert’ to support SSL. Then there is the Define IMAP_FOLDER_CONFIGURED which has to be set to true, after checking the Defines below that, are matching the folder structure in your IMAP. (I don’t know if I have a standard config there, so I’m not giving my config here, but if I open the folder in roundcube the folder name is displayed as variable _mbox in the URL.

      Restarted the Webserver and checked if I could access https:///Microsoft-Server-ActiveSync This should ask for username and password (use the data for an E-Mail-Address). After that you should get an error message stating “GET not supported”. If another error message is displayed the error should give hints about wrong configuration. And if you only get an error 500 or something like that, the Logs are your friends.

      At this point the Server should support Pushmail. Now the mobile has to support it, too. I am using K-9 mail for android and it works fine.

      I hope this is enough for anyone wanting the feature to get started.

    I went through the Buster guide and I’m very happy that it’s really easy and fast-forward.

    I subscribed last year professional email boxes to an ISP and when I used mx-tester, the quality of outbound mail was 3/10 and unlikely not to be delivered elsewhere than spam boxes.

    I run “real” SMTP because my project needs more than sending newsletters and an email API is just not the right call for that.

    As per use case, I will have a small business run with one domain and 10-20 users and i’m pretty confident it’ll do the job well without me buying a Google Suite access or cloud-base solutions. I’m not a big believer of having personal data “somewhere” in the cloud, stored in conditions I can’t check.

    So, this guide is a great opportunity to catch up on Email hosting.

    Big Thanks Christoph !

    P.S.: For those who looks for an interface you could pick up a GUI or take a look at a web API i’m starting : https://github.com/Gompali/ispmailadmin-api. It’s still beta but may work as soon as possible. Feel free to contribute.

      Thank you very much for the feedback. The API looks promising. I will surely take a look soon.

    Just a general thank you and a success story. With only a few bumps on the way I made it, and moved our small but ancient (really: qmail+vpopmail circa 2004 vintage) server to ISPmail (imapsync helped enormously – the only way to migrate from something that different). Works like a charm, really excellent tutorial.

    Hi Christoph,

    I have setup my Family email server in 2005 with Sarge. Since then, I was always doing inplace Upgrades. These days I found your updated buster guide and decided to start now again with a blank install. To learn something new, I use postgres as a backend. I hope migration will be done in some days, as I only spent here and there an hour on it.

    For me this is one of the best guides ever seen, as it serves the need of professionals, but also newbies by explaining the context and giving additional background Information.

    Many thanks
    Matthias

    PS: I will keep my existing dbox format and not migrate to Maildir;-)

    Hi Cristoph,

    Thank you very, very much for this amazing documentation. I just configured my VPS here and it’s working flawlessly. In fact, this documentation is so good that I’ll redo another VPS that I manage here and it’s a little messy. 🙂

    I loved the inclusion of the theory of how mail servers works! And you have a very clear language. I’m a Brazilian Portuguese native speaker and understood everything.

    Hope you continue to update this guide for the next Debian releases. 🙂

    Best regards!

    Thanks for this awesome tutorial! I have my mail server up and running on my Raspberry Pi 4 with an attached SSD for mail backup purposes. I use an additional Raspberry Pi as a local DNS server (with Pihole and Unbound) that handles the mail server’s spam queries (instead of sending them out to my ISP’s DNS servers). I’m a residential Comcast customer so I had to set up a relay through their smtp server to send outgoing mail, and I have to use dynu.com as an incoming relay because Comcast blocks port 25. But your server set-up has proven to be rock solid despite these local workarounds. I particularly appreciate the info on DKIM and SPF record set-ups. Those are the little touches that actually make the mail server usable in the real world. Thanks!

    Hello,

    This guide is all i was looking for to learn linux.
    It introduced me to mailservers, tought me how they work + made me configure it.

    I am pleased to say that my mailserver is now running smoothly.

    It was done just for learning purposes, but man this guide helped alot.

    PS The email address used to post this comment is hosted on the newly installed server.

    Thanks a lot!

    @Christoph: do you have experience about adding Dovecot full text search that you can share with the community? This is probably “the one missing feature” to more easily say goodbye to gmail et. al.

      Indeed. I wonder how that dropped off my todo list. Let me see what I can provide.

      Seems that I managed to get the Solr search engine plugin working. I’m currently indexing my family’s mail server with 27 GB of emails. Let’s see where that ends. 🙂 A quick text with a single mailbox and a full-text search from Thunderbird was lightning fast.

          Funny. Mine is very similar. I have tried with Tomcat and Jetty first though until I learned I don’t need that. And I was shocked to see that the Solr version in Debian is from the stone ages. Besides the Buster version has been vulnerable for over a year because of CVE-2019-0193.

          I only did a few details differently: https://pastebin.com/raw/acS77Y5z

          What bothers me is that I don’t see Dovecot talk to Solr (in tshark) when I search from Thunderbird. I still need to figure out if it’s using everything correctly.

    Vielen dank Christoph! My brand new e-mail server is running better then ever on a clean Ubuntu 20.04 server with all previous emails migrated from the old server. It’s only managing 4 domains for the family and a handful of friends and accepting mails for a long list of aliases, so nothing too fancy.

    Your tutorial was fantastic. Not only did you explain What to do and How, but also Why. The result was I learned a great deal of new stuff and truly enjoyed the whole learning process.

    DKIM was new to me and makes the server much more usable than my previous setup.

    Thanks again for your time and effort, you really created a high quality tutorial here, by far the best I have come across on the net…

      That’s feedback that makes my day. 🙂 Thank you for taking the time to report your success.

      Most of the servers I deal with have just 10-30 users, too, by the way. But don’t worry. We will be ready when managers realize that moving into the cloud was utter idiocy and we will help them get their emails back under control. 🙂
