Hi list, I'm sorry, but I am not sure if thi is OT or OT. :) I am having problems where postfix does not deliver to all recipients if the message has multiple recepients. This does not always happen, but sometimes (I daresay almost always). Has anyone experienced similar problems? All tips are velcome :) Tarjei Setup: Postfix (mta) -> avplinux(antivirfilter) -> postfix -> cyrus master.cf (postfix): filter unix - n n - - pipe flags=R user=filter argv=/opt/AVP/kavkeeper/kavkeeper -s ${sender} -r ${recipient} -m sendmail cyrus unix - n n - - pipe flags=R user=cyrus argv=/usr/cyrus/bin/deliver -e -m ${extension} ${user} cyrus.conf: # at least one LMTP listener is required for proper delivery lmtp cmd="lmtpd" listen="lmtp" prefork=0 lmtpunix cmd="/usr/cyrus/bin/lmtpd" listen="/var/imap/socket/lmtp" prefork=0 }
