Hello,

We recently ran into a problem with our current configuration where a post fix loopback error occurs. This is a secondary server that will relay only to users on the network, as our settings will show. On a side note the workgroups are not intergrating into the user list under server admin / mail. Our configuration settings / Error logs are as follows

So,
Seconday domain for mail is mail2.webster.k12.mo.us


Code:
Sep 14 13:53:55 localhost postfix/smtpd[1028]: disconnect from mail.webster.k12.mo.us[204.184.92.241]

have you added mail2.webster.k12.mo.us to the local host aliases in server admin/mail/advanced tab/hosting tab ?

What does the second server do, play smtp server or also local mail server. Have you set the domain names properly ?

Using e.g. ip-numbers in stead of names does not make it clearer. What are the links between the 1st and 2nd mailserver ?

Thx, kees
