Firewall stops Win2K email
I've got a problem with a Windows 2000 server (well, apart from the fact that I'm forced to admin it
I've setup a firewall in front of the machine and have locked it down to only let through web, ftp, dns, vnc, etc. Everything else is blocked.
The problem is that even though I've let port 25 tcp out, email will not send from the box (just stays in the queue).
Only when I allow all tcp traffic out will the emails send.
The mail software is "MailEnable" and it's setup to send using port 25 (dur!).
Does anyone know of any ports which I need to leave open to make it work, since I don't fancy sitting here trying every combination possible
