Hello :)

It's possible the remote mail servers have blocked traffic from your IP address. Check with telnet to see if that's the case. EX:

Code:
telnet remote-mail-server.com 25
Replace "remote-mail-server.com" with the hostname of the remote mail server you are attempting to send to.

Thank you.
