This is a CentOS 4 based install, with the Zimbra Commmunity edition, version 4.5.1. Zimbra is running fine, managing domains, and its great stuff.

What I have noticed is that since installing Zimbra, logwatch stops sending mail to the root user. The Zimbra daily mail reports are making it fine, however

Logwatch is set to use /bin/mail and from what I can tell, /bin/mail isn't exactly working (since postfix/sendmail is disabled on the system in favour of having all mail handled by Zimrbra's postfix).

Should I set logwatch to use something rather than /bin/mail?

From what I can tell, this thread might be related: http://www.zimbra.com/forums/showthread.php?p=40424

As will this thread: http://www.zimbra.com/forums/archive...php/t-180.html however that test of sending mail within the zimbra user, fails for me

Any help to getting logwatch working again, would rock? Its true, /bin/mail is not writing to zimbra's queue. Running mailq as the zimbra user shows no mail, but running mailq as root, I see "postqueue: warning: Mail system is down -- accessing queue directly" and there's a good 100+ messages waiting to be delivered (mainly logwatch, i presume)

Sendmail is not installed, postfix is postfix-2.2.10-1.RHEL4.2.mysql_pgsql.c4 but disabled (in favor of the zimbra version)

Any help will be greatly appreciated. Thanks
