When the Sieve plugin tries to send a vacation message or redirect a message to another address it fails.
dovecot: lmtp(6412, user@example.com): Error: lmtp client: DNS lookup of orange.example.com failed: connect(dns-client) failed: No such file or directory dovecot: lmtp(6412, user@example.com): Error: dAIOClYSJE8MGQAAhQ0vrQ: sieve: msgid=4F241255.2060900@example.com: failed to redirect message to admin+user@example.com (refer to server log for more information)
But the dns-client sockets are created when Dovecot starts up:
# find /usr/local/var/run/dovecot -name dns-client -exec ls -l {} + srw-rw-rw- 1 root staff 0 Jan 28 16:15 /usr/local/var/run/dovecot/dns-client srw-rw-rw- 1 root root 0 Jan 28 16:15 /usr/local/var/run/dovecot/login/dns-client
Hum, is it Dovecot or Pigeonhole (dovecot-2.1-pigeonhole 1600:b2a456e15ed5)?
