In order to keep this diary blog updated I should add a small note about mail servers. I’m still doing some sys admin work for about 2 hours a day.
After a lot of experimentation I finally have one mail server up and running with Postfix and Dovecot.
Besides the official documentation I usually try to read at least one book about the tools I’m working with. Safari led me to Postfix: The Definitive Guide by Kyle D. Dent. The book gives a good overview on how Postfix works and goes through several different configurations that you may be interested in implementing. The only problem is that the book is outdated (December 2003) – that’s last decade!
Everything seems to be running ok but running and maintaining a mail server is a lot of work. There are just so many details and configurations that can go wrong. Performance, Security, Authentication, Disk space, Spam, Anti-viruses… The list is huge. I’m looking forward to meeting the next sys admin to join our team.
I’m working on a project that offers domains and email accounts to the final client so it’s been a good experience to understand how mail and dns servers work. We have a lot work ahead!
