It’s no secret that configuration for OpenSMTPD changed a lot with version 6.4.0. Despite the fact that changes were announced long time ago and that many configuration examples have popped-up, my particular usage wasn’t covered(1).

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...
I want to have a look at a replacement for my Postfix/Dovecot/OpenLDAP mail server using the OpenSMTPd implementation.

Like I did with NetBSD, this is how to build an almost complete Mail Server with OpenBSD.
We’re gonna use a Dovecot IMAP server and a Postfix SMTP server. Postfix will use Dovecot as a SASL service. Both will use LDAP to identify valid users and e-mail aliases. Mail sanitization will be provided by RBL, from Postfix, and by the spamd shipped with OpenBSD.Continue reading...
