Postfix is writing to the unix socket but nobody reads from the socket or Cyrus is reading from the socket but nobody is writing to it ? I've seen this with Exim. Exim sends the DATA phase and never hears back from lmtpd. It only happens for specific recipients, so the only effect is that mail delivery is stalled for some users. Restarting "master" seems to fix it: a bit heavy, but fine for most people, as most IMAP clients just re-authenticate. Fussy clients (like mine ;) tell you something's awry. This is a small internal mail system which is stopped every evening and restarted the following morning. Despite of that there is no delivering at all. How do you know Exim never hears back from lmtp ?  I only have the lmtp read timeout message. Is there a way to enable more information output ? Regards, Marek
