This works quite well. I did try to do what you did with LTMP, but that just wasted time. In the end, I was happy how opensmtp handled the lda connection, thus didn't mind deviating from the recommended dovecot setting.

As workaround, you might use a userbase table (see smtpd.conf(5)) to map all your virtual users to a single (fake) system users. Also, you might play with deliver to lda instead of lmtp.

Virtual users need to exist in /etc/passwd ?
Hi, I have configured OpenSMTPD 5.4.4 (from OpenBSD 5.7) with virtual LDAP users and LMTP to Dovecot. table vusers ldap:/etc/mail/ldap.conf table vdomains ldap:/etc/mail/ldap.conf accept from any for domain virtual deliver to lmtp "/var/dovecot/lmtp" If the user id exists in /etc/passwd, the mail is accepted by OpenSMTPD and delivered to dovecot. Dovecot only uses LDAP so it doesn’t care about users not being in /etc/passwd since they exist un LDAP ; tested using direct telnet on LMTP port. If the user id does not exist in /etc/passwd (but exists in LDAP), the mail gets rejected by OpenSMTPD with error « 550 Invalid recipient ». Is this expected or does it reflect a miss-configuration on the LDAP size ? Sounds weird to me that virtual user must exist in /etc/passwd :) TIA, Jo
