Sending mail from both webmail accounts (on the servers) works as expected. Any ideas?
First, I would test if you can reach the mailserver at all:
telnet smtp.gmail.com 25
If this succeeds, then nstall tcptraceroute (or something similar) and run it against the mailserver/port you're trying to reach. It will show you where your packets are being blocked and thus help you to narrow down the underlying cause.
Example: tcptraceroute smtp.gmail.com -p 25
