Hi guys,
I'm seeing this in the logs:

lookup failure;
e-mail addresses in the above is, of course, fictitious.
donny_bra...@example.co.uk is hosted elsewhere, sa...@some_domain.com
is hosted on this box. The server is running RHEL5, with the stock Red
Hat rpm recompiled with mysql support.
The mysql database sits on another server, and is mostly idle (the
Postfix box has very low traffic so far). I am unable to reproduce any
query problems outside of postfix. Doing the queries directly in the
mysql shell just works. The following also works 100%:
# postmap -q sa...@some_domain.com
mysql:/etc/postfix/mysql_virtual_alias_maps.cf
sa...@some_domain.com
I have verified the usernames/passwords in the mysql_*.cf files.
Nothing was changed in the last few days. So I have two questions about
the above:
1. What could possibly cause postfix to have lookup problems when
nothing else does? The server did run out of disc space a few days
ago. I did a postsuper -s -v which didn't show any problems. Could the
disc space issue have damaged something?
2. Is there a way to enable debugging output for connections from apache?
3. I looks like the query fails when the mysql connection has timed
out. Can postfix be told to reconnect automatically instead of
accepting it as a failure?
Thanks
