Quite possibly, your mail server doesn't have a valid reverse lookup record. If this is the case, you'll have the same problem I did originally - You can read, but not post... you whould get a message in 24 hours or so saying something like: Mail Undeliverable and containing lines that look like: >>> RCPT To: <<< 450 Client host rejected: cannot find your hostname, [xxx.xxx.xxx.xxx] ... Deferred: 450 Client host rejected: cannot find your hostname, [xxx.xxx.xxx.xxx] There's only three solutions to this: 1) Get on your ISPs back... annoy the hell out of them until they fix it. 2) Switch ISPs to one that DOES have a reverse-lookup for their mail server OR (And this is the trickiest option) 3) If they have a valid reverse lookup for their users, but none for the mail server (Don't laugh, I've seen this) set up your own SMTP server using sendmail, and send all your mail through it. If your using the FreeBSD system as a NAT box or something, you'll have to allow it to relay from your local network... and ONLY your local network. If you allow anyone else to relay, they will.
