Thanks again for the help everyone. I setup these postfix servers about
5 years ago. I've pretty much ignored then except for postfix updates
since then. I know this probably wasn't the best idea but I got moved
into a different department and could barely keep up.
Now I'm back and have the chance to do a complete re-install to new
server hardware. I'm just wondering if anyone out there has some how to
or best practices to follow. I'm going to use a Ubuntu 11.04 server
install. I've got about 15 domains to accept mail for and just over
1000 users. I'm not worried about the setup of mysql/virtual server as
I've done that a few times. My main goal is to figure out what I should
have in each section of main.cf (smptd/client restrictions to help stop
spam and not to be a open relay or back scatter host.
Thanks.
