Sam,
I've installed Courier (version 0.65 from FreeBSD ports) on our web server
as replacement for sendmail. It's only purpose is sending mails generated
by local PHP scripts - no incoming SMTP, users, auth, etc. At the first
glance everything was OK, however after some time webmasters started
complaininig about lost (sent but not delivered to recipients) messages.
Searching maillog revealed nothing helpful.
After some digging around I've recognized that lost messages had "bad"
headers (with non-ASCII characters) and/or body. Setting BOFHBADMIME=accept
and MIME=none solved this problem, but some messages still was not get
delivered. I've found out that body of these messages had too long lines
(>5000 chars). And still nothing in the log.
So questions arised:
1 (most important). Why local sendmail silently discards "bad" messages
without writing any errors to syslog?
2. Shouldn't "bad MIME" checks be applicable only to the messages received
by incoming SMTP for delivery to local users, not for outgoing messages?
