I have a qmailtoaster that's been running without problems for a while. I haven't made any configuration changes, and the server is healthy, with enough disk space available etc.
Today, I noticed that certain expected messages are not getting delivered. Lots of mail is still coming in without problems, but certain transactions are failing silently. The normal pattern that I see in the logs for a healthy delivery looks something like: tcpserver: pid 2356283 from 123.123.123.123 tcpserver: ok 2356283 s6:111.111.111.111:25 :123.123.123.123::40631 CHKUSER accepted sender: from <otheru...@gmail.com::> remote <mail- qt1-f176.google.com:unknown:123.123.123.123> rcpt <> : sender accepted CHKUSER accepted any rcpt: from <otheru...@gmail.com::> remote <mail- qt1-f176.google.com:unknown:123.123.123.123> rcpt <myu...@mydomain.com> : accepted any recipient for this domain policy_check: remote otheru...@gmail.com -> local myu...@mydomain.com (UNAUTHENTICATED SENDER) policy_check: policy allows transmission simscan:[2356286]:CLEAN (-0.30/100.00):1.9436s:Re_ Some Topic:123.123.123.123:otheru...@gmail.com:myu...@mydomain.com mail recv: pid 2356286 from <otheru...@gmail.com> qp 2356287 For the problem ones, it gets as far as: CHKUSER accepted sender: from <otheru...@gmail.com::> remote <mail- qt1-f176.google.com:unknown:123.123.123.123> rcpt <> : sender accepted and then stops. There's no "CHKUSER accepted any rcpt" and the delivery never completes. This doesn't seem to be connected to the actual recipient: all recipients receive some mail, just not all of it. However, specific incoming messages appear to fail consistently. Has anyone encountered this? And do you have any insight into what could be causing an apparent failure between sender acceptance and recipient acceptance in CHKUSER? What tests does CHKUSER perform to determine if a recipient is accepted? Thanks for any help or suggestions, Angus --------------------------------------------------------------------- To unsubscribe, e-mail: qmailtoaster-list-unsubscr...@qmailtoaster.com For additional commands, e-mail: qmailtoaster-list-h...@qmailtoaster.com
