Dovecot
Looking at my notes , it seems I haven’t setup an email services server from scratch since 2015. Of course, mine have evolved following OpenBSD updates and upgrades.
Let’s benefits from the fact that I’m migrating from Vultr to OpenBSD Amsterdam to write a few notes about the mail server (re)creation. At the time of writing, OpenBSD is available in version 7.2.Continue reading...
I’ve just discovered than compression can be applied on Dovecot mail storage. Truth is I used to run the delivery via Postfix. Now that I use OpenSMTPD and Dovecot LMTP to deliver the mail, those can be compressed for write (LMTP) and read (IMAP) process. Here’s how.Continue reading...
Looking to replace my old Postfix/Dovecot configuration with more native OpenBSD stuff, I finally ended with a configuration than seems suitable to me. I’ll be hosting virtual users and mail aliases in ldapd(8), smtpd(8) will deal with email receiving/sending and dovecot(1) will be in charge of email delivery using LMTP and email reading using IMAP. Of course, spamd(8) will do a bit of work in front of OpenSMTPD. All of those will run on OpenBSD 5.7.Continue reading...
Those are my notes about configuring OpenSMTPD 5.4.4 and Dovecot 2.2.15 on OpenBSD 5.7. I’ve setup virtual domains and users. In this simple configuration, the virtual users are matched with local users for mail delivery. SMTP submission is authenticated and passwords for all mail services are stored in usual system files. Of course, mail reception is protected by spamd. Here are the directions.Continue reading...
My actual Mail system is running OpenBSD. I use the good old “put the bits together and rule the configuration files” way. But there are some times when I fell like a Web GUI would be nice. I never liked solutions like Zimbra or Zarafa so much because they were quite restrictive bundles - it terms of which backend could be use. But that’s what they’re selled for: bundles.
Let’s have a look at what mailserv does and how.Continue reading...
