No such setting in my main.cf so I assume it's empty. Anyway, I looked at some of those mails that postfix was trying to forward, and they were old and unimportant, so I purged them. Let's see what other problems I've made for myself... :) -- Regards, Peter.

Just the one "mydomain" -- Regards, Peter.

The config entries I changed from default are: --- main.cf --- myhostname = mydomain = myorigin = mynetworks = smtpd_relay_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination --- Also, are all emails sent to "mydomain" or do you have additional domains configured?

No, $myhostname is .lan Like you I've had some trouble in the past, so a lot of this is from trying and failing, but it works as I want it now, so I'm happy-ish. Regards, Arve

Two other > hosts' mails never show up anywhere. I'm not sure I quite understood where you're having problems, but I have a machine that accepts mail from the LAN through postfix, so I'll show some of my setup. Replace any <> with your hostnames. On the LAN machine I don't have postfix, I only send mail directly to the machine with 'sendmail', but I found that I have in /etc/mail/mailertable: 192.168. smtp: esmtp: And in /etc/mail/local-host-names I have set - maybe that does something, but I send mail directly with sendmail either way. On the postfix machine I have in /etc/postfix/aliases: root: arve This should make all mail to root be delivered to me. It also contains a bunch of aliases that I'm not sure if is necessary: arve@ arve arve@.lan arve arve@.localdomain arve arve@.lan arve In /etc/postfix/main.cf there is this, and I assume at least some of this makes this all work: myhostname = .lan inet_interfaces = $myhostname, localhost mydestination = $myhostname, localhost.$mydomain, localhost, mynetworks = 192.168.0.0/24, 127.0.0.0/8 Regards, Arve
