Relay certain domains in the sender part by defined ip addresses
Hi there! I am using Postfix 2.6 along with GNU Mailman for mailing lists. My question is if there is any way to relay e-mails with sender (MAIL FROM) of defined domain names (eg. x(a)domain.tld) originated by a predefined set of ip addresses and reject all the others that originate from other ip addresses. ... 7 Apr 2010 02:25
Am I really using a CIDR map?
For some time I have been tracking changes to the access table with RCS. Each time a change is made the "ci access" results in the removal of the access file from /etc/postfix and leaving the /etc/postfix.access.db file.

Spam filtering problem [Probably really a BIND problem, but let's not poison the well...]
Ok, I started down this path a while back and left it on the shelf - but now I'm back on the case, but I'm still baffled and don't know where else to ask. If you'd point me in the right direction, I'd be very grateful. I'll also include the problem here so you can take a crack at it too. --- In short, I'm gett... 6 Apr 2010 01:00
