Hi,
I m a newbie with exim, any suggestion is highly appreciated.
Here is the descriptoin.
I m running exim 4.42 with cyrus-imap2.2 and sasl2 in FreeBSD 5.3.
Authtentication with imap2.2 is fine. I can login to it without problem.
The only problem is when I send email thru Exim, it failed to
authenticate due to the top level domain name (domain.com) is not found
for the local IP address. The error is as follow:
# tail -f /var/log/exim/mainlog
2004-10-12 10:51:00 unexpected disconnection while reading SMTP command

Of course the dns setting does not have IP associated with the top level
domain name, but only with the FQDN, that is eg. host.mydot.com
The following output from exim shown that the local IP 192.168.4.254
(the one has the exim and imap server hosted) is assoicate with
at.mydot.com:
# exim -bh

220 at.mydot.com ESMTP Exim 4.42 Tue, 12 Oct 2004 11:10:06 +0800
the following command shonw that mydot.com is really refer to at.mydot.com:
# host mydot.com
mydot.com mail is handled (pri=10) by at.mydot.com
# host
at.mydot.com
at.mydot.com has address 192.168.4.254
Can anyone help me to resolve this problem?
Thanks
