Hello,
I've tried to migrate some 90 servers from Sendmail to Postfix, trying
to keep the behavior as similar as possible. They were all simple null
clients, sending mail via relayhost only. After some time I've noticed
that some servers are sending their daily logwatch outputs with
From: "r...@n2rhps88.localdomain" <r...@n2rhps88.localdomain>
, while others have
From: Root n2rhps23 PGRLF <u...@o2bs.com>
. I prefer the second variant; the problem is that configurations are
the same... The "comment" field in this record comes from /etc/passwd.
[r...@n2rhps88 ~]# postconf -n
