Hi,

I have a sendmail server which was becoming underpowered for my needs. So I
set up a brand new server, moved all of the user accounts and mailboxes over
to it, then assigned it the hostname (mail.jellico.com) and IP address
(207.191.185.6) of the old server. I changed the hostname and IP address of
the old server to something different (207.191.185.3). This is working fine
except I have noticed a few (very few) pieces of email still getting
delivered to the old box for whatever reason. I figured this would be easy
to fix so I changed /etc/mail/mailertable from
jellico.com local:

to
jellico.com smtp:mail.jellico.com


remapped mailertable.db, restarted sendmail and tested it by sending mail
from root on the old box to steve [at] jellico.com It still got delivered
locally. (sendmail -bt confirmed that the mail would be delivered locally).
Next I removed jellico.com from /etc/mail/local-host-names (it is still in
relay-domains) restarted sendmail and tried again. The mail is not being
delivered locally anymore, it isn't being delivered anywhere. sendmail -bt
verifies that the mail should go where I want it to:

[root [at] Raydeus-Dee mail]# sendmail -bt

but the mail actually bounces. In /var/log/maillog I see this:

The mail is looping back. What have I overlooked here?

1) Your sendmail rewrites steve [at] jellico.com to steve [at] mail.jellico.com
2) The host is the best MX for mail.jellico.com but mail.jellico.com is
not on its list of local email domains

Find out *WHY* the rewrite occurs:

echo '3,0 steve [at] jellico.com' | sendmail -d21.12 -d60.5 -bt

-d21.12 - more detailed tracking R lines processing
-d60.5 - tracking of map lookups

Hi again,

The old machine still thinks it is mail.jellico.com. See below. Where is
this coming from if not local-host-names?

The old server is seeing what it considers to be its own host name in
the greeting from the new server, and deduces that "it's talking to
itself". This shouldn't happen if you actually changed the host name of
the old server and restarted sendmail there - unless you're (against
recommendations in the docs) hardwiring the hostname in the sendmail
config via confDOMAIN_NAME in the .mc file.

A short-term workaround is to add the 'k' flag to the SMTP mailer
definitions on the old server:

MODIFY_MAILER_FLAGS(`SMTP', `+k')

See also FAQ 4.5 (at the very end).

Hi Andrew,

I'm not sure exactly what this is telling me, but I think the problem is (as
I stated in my reply to myself here) that this old server still thinks it is
mail.jellico.com. It's hostname is raydeus-dee:

[root [at] Raydeus-Dee rc.d]# hostname
Raydeus-Dee

I need to convince it that it is NOT mail.jellico.com. I have checked my
DNS, the A record for mail.jellico.com does point to the correct IP address,
207.191.185.6. I believe the problem is in my sendmail configuration
somewhere, but where?


[root [at] Raydeus-Dee rc.d]# echo '3,0 steve [at] jellico.com' |
sendmail -d21.12 -d60.5 -bt
WARNING: local host name (Raydeus-Dee) is not qualified; fix $j in config

I rebooted the box and it works now. Don't know why. I did stop & start
sendmail so it should have read the configs and a reboot sdhouldn't have
been necessary, but it's working now. Thanks for the responses.
