I'm running Ubuntu 8.04 and have installed logcheck. Logcheck usually sends it's email through exim or some other MTA. My system mail, i.e. root@localhost, is not being picked up by zimbra.
I've adjusted my /etc/aliases - root: firstname.lastname@example.org
I've tried adding: set sendmail=/opt/zimbra/postfix/sbin/sendmail to my /etc/mail.rc
I've even tried moving /usr/sbin/exim4 and sym-linking /opt/zimbra/postfix/sbin/sendmail. So, that zimbra's sendmail would be called in place of the standard MTA for my system...
However, when then postfix complains about: status=bounced (mail for mail.thisdomain.com loops back to myself)
I remember having this working properly in my last install with Zimbra 5.02. Any hints?
