While migrating an old woody machine to a new sarge machine (new
hardware etc) I decided to change over from sendmail to exim4.
The migration went _very_ smoothly - up to now I've not had a problem
- but we've recently noticed one issue.
Outgoing mail from the server (my home address) sent to my work
address bounces with the message:
------------------------------------------------------------------------
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es)
failed:
[EMAIL PROTECTED]
all relevant MX records point to non-existent hosts
------------------------------------------------------------------------
So - I ssh'd in to my mail server.
host -t MX work.domain
returns
work.domain mail is handled by 10 mail.work.domain.
Then
telnet mail.work.domain smtp
returns
Trying <mail.work.domain IPADDR>...
Connected to mail.work.domain.
Escape character is '^]'.
220 mail.work.domain ESMTP Sendmail 8.12.3/8.12.3/Debian-7.1; Tue, 7 Jun 2005
11:13:08 +0200; (No UCE/UBE) logging access from: my.mail.server(OK)[EMAIL
PROTECTED] [<my.mail.server IPADDR>]
So - on the box where exim is running - the MX query returns the
correct host and that host is answering smtp.
Since I'm new to exim4 I've no idea how to start debugging this.
No other domains that I can see have this problem - at least nothing
in the /var/log/exim4 directory.
