This is /etc/hosts. There's not much in it.

/etc/hostname contains just the line
- that's all.
It seems that Postfix or SpamAssassin just ignore /etc/aliases (and also the postfix forwardings table). I see that all notification mails are always sent to and from firstname.lastname@example.org
. I assume that root
is because that's the user running postfix and spamassassin. And I guess @cesinge.com
because it's the DNS domain to which the machine belongs?
What bothers me is that I don't have a clear understanding of how this works. Then I could consider tweaking something to force these mails to a mailbox that I read.
