The server is capable of sending mail. Its setup the same as the ideas
server.

Hmm. IDEAS should not have mail. Make sure SPF records are there for all
aliases.

All of our servers are capable of sending mail whether they actually do or
not. If this is not what you were referring to, then I'm not sure what was
meant.

OK. I just do not want unnecessary ports open. I still remember the sendmail hack from Montreal.

The only ports that will be open to the public are 80 and possibly 443. The firewall (managed by automation) must be configured to let anything else through.
