delivery errors

[lenny at edpausa.com]

a couple times every hour this comes up in the log for some of the users and
the sender gets a bounce back with complain about delivery to
/var/imap/socket/lmtp. This seems to be very random and while this happens
with less then 5% of mail traffic, some important stuff bounces for no
apparent reason. The install is cyrus 2.2, recently upgraded from freebsd
ports from 2.1 via portupgrade.




relay=/var/imap/socket/lmtp[/var/imap/socket/lmtp], delay=0,
status=deferred (remote protocol error in reply from
/var/imap/socket/lmtp[/var/imap/socket/lmtp] while sending end of data --
message may be sent more than once)
