Hello,
We have recently started to experience an inconsistent problem after
restarting cyrus and sendmail after a nightly backup script runs. All
services seem to start properly, but mail delivery is deferred with
sendmail logging
dsn=4.4.1, stat=Deferred: Connection refused by localhost
It appears to be something in lmtp, but we aren't sure what exactly. We
are using the socket for lmtpunix delivery. The magic bullet seemed to
be stopping all services and removing /var/run/cyrus-master.pid and some
old lmtp lock files, but then this may have been coincidental. I found
a few similar reports on Google, but no definite answers to this problem.
Any insight as to why this would just start happening out of the blue
would be most appreciated.
Thank you,
Chris Harms
