I'm running postfix + dovecot on my CentOS-7 home server. When I send myself a message I get this error message in /var/log/maillog: Aug 9 12:59:57 alfred postfix/lmtp[31336]: B0D02220748: to=tim@localhost.gayleard.eu, orig_to=tim@localhost, relay=alfred.gayleard.eu[private/dovecot-lmtp], delay=475, delays=474/0.03/0.02/0.09, dsn=4.3.0, status=deferred (host alfred.gayleard.eu[private/dovecot-lmtp] said: 451 4.3.0 tim@localhost.gayleard.eu Internal error occurred. Refer to server log for more information. (in reply to RCPT TO command)) and in /var/log/dovecot I read Aug 09 13:13:03 auth-worker(31472): Error: passwd(tim@localhost.gayleard.eu): getpwnam() failed: Address family not supported by protocol Aug 09 13:13:03 lmtp(31470): Error: user tim@localhost.gayleard.eu: Auth USER lookup failed
It seems that USER is set to tim@localhost.gayleard.eu rather than tim .
I am including the line mailbox_transport = lmtp:unix:private/dovecot-lmtp in /etc/postfix/main.cf . If I omit this line so that postfix sends email directly to ~/Maildir I have no problem - except that spam is not being filtered.
I give the output of postconf -n below.
Any advice or enlightenment gratefully received.
