Hi List, I've been running Courier for some weeks now, and am now gearing up to do a larger scale beta test (company wide). But I still have some questions. I was working on firewalling the mail system and I would like to know if the Submission port (587/tcp open submission) needs to be accessable from the outside.
Currently I have closed everything but pop3/pop3s/smtp/imap2/imaps/http/https and submission. But is submission used by 'outside' processes, or only from the local system (the webmail and imap processes) ?? Can I safely close or leave open this port...
