Hi,
I've got a vanilla Postfix on CentOS 6.3:
[root@dc ~]# rpm -qa | grep postfix
postfix-2.6.6-2.2.el6_1.x86_64
It's not a major mail server, just being used to redirect local mail
using a /root/.forward file.
I have other similar systems, running without problems. This one however
throws an "unknown mail transport error" when delivering local logwatch
messages (the only ones generated currently).
Can anyone suggest some solution? I've tried various things (emptied the
queue, configured particular inet_interfaces) without success.
Thanks in advance,
Nick
