We’ve got an email system based around Cyrus etc. The ‘Out of Office’
or Vacation facility doesn’t seem to be working reliably. From what I
can test, it seems that if a user on the LAN sends to another internal
email user who has set a Vacation message, then they will receive
notification that the intended recipient is out of the office. The
Sieve script is in /usr/sieve/f/fred/default and also msg.script in
the same directory. However, when I send to a user with a set
vacation message using an external email system (eg Hotmail) then it’s
a bit hit and miss as to whether an out of office message gets
delivered to the sender. I’ve set up a test user and created a
vacation message, and at present no out of office messages are being
delivered, although I’m almost certain they sometimes do get through.
The system has been in place for a few years, and I’ve had a couple
of users mention that it didn’t always work, but I’m only just getting
around to investigating things in more detail. I’ve looked at the
header of an incoming message in the recipient’s Cyrus folder which
should be generating an out of office message, and the ‘To’ and ‘From’
fields look okay, plus there is an X-Sieve: line. I’d appreciate some
help in trying to track down what’s going on. I’m not sure if the out
of office message is being generated but not delivered, or if it’s not
being generated at all. Are there any logs I can check, or traces I
can set up?
I had the same issue as you said: vacation thing works for internal network,
but not 100% works for external network(senders).
I fixed it some time ago. The problem is my incoming
server(sendmail+cyrus-imap)
itself can not 100% send emails to outside! It's blacklisted! it's not
strange
because I have a separate outgoing server. I'm not expecting my incoming
server
to send anything out. To fix the problem, first reconfigure sendmail to
reject emails
on MTA level, and then reroute emails coming from my incoming server
to my outgoing server. This will make sure my incoming server can send
emails to outside.
That's it.
Allen.
