Not too sure what the problem is, but I had to use '127.0.0.1' in place of
'localhost' for my virtual_transport setting to work. 'localhost' is in
/etc/hosts ('127.0.0.1 localhost.localdomain localhost'), and
a 'ping localhost' at the command line works.
This is the line in the log that caused me to take a look:
Apr 1 05:07:55 mail postfix/lmtp[15053]: 3055B200083: to=<localemail>,
relay=none, delay=172, delays=172/0.02/0/0, dsn=5.4.4, status=bounced (Host
or domain name not found. Name service error for name=localhost type=A:
Host not found)
This error went away once I used ''virtual_transport = lmtp:inet:127.0.0.1'
I'm not exactly expecting that lmtp should attempt a dns resolution and
ignore /etc/hosts, given the following note in master.cf:
# ====================================================================
#
# Recent Cyrus versions can use the existing "lmtp" master.cf entry.
#
# Specify in cyrus.conf:
# lmtp cmd="lmtpd -a" listen="localhost:lmtp" proto=tcp4
#
# Specify in main.cf one or more of the following:
# mailbox_transport = lmtp:inet:localhost
# virtual_transport = lmtp:inet:localhost
#
# ====================================================================
This is from a postfix 3.0.0 source install.
