Sorry for all the notes;
I'm trying to have postfix 3.4.8, trying to authenticate postfix against
Dovecot 2.3.4.1 passwd-file, using lmtp.
Not sure if I'm failing because of a smtp failure or I'm not getting
authenticated by dovecot.
main.cf
virtual_transport=lmtp:unix:private/dovecot-lmtp
_*postfix log*_
connect from unknown[192.168.212.227]
Apr 28 13:42:14 mail3 postfix/smtpd[21859]: lost connection after EHLO
from unknown[192.168.212.227]
Apr 28 13:42:14 mail3 postfix/smtpd[21859]: disconnect from
unknown[192.168.212.227] ehlo=2 starttls=1 commands=3
I keep getting smtp timed out, it takes a while, but does time out.
