I use Gmail with IMAP access and use GMail's SMTP for outgoing messages.  Works fine for me on Cox.  Thunderbird client.

I have a new favorite picture on the internet.

Well HostGator who hosts TeensOnLinux.org and supertunaman.com
allows SMTP through port 26 as opposed to 25, so mai Thunderbird works
just fine!

...for now...
