smtp

Sending mail via smtp.gmail.com is failing on my server. I looked on some forums and people were saying to make sure you can telnet to the smtp address first.

When I telnet from my server i input this and get this error:

[root@localhost ~]# telnet smtp.gmail.com 465
telnet: smtp.gmail.com: Temporary failure in name resolution
smtp.gmail.com: Host name lookup failure

From my OS X desktop I do the same and get this:

    Macintosh-3:~ joe$ telnet smtp.gmail.com 465
Trying 74.125.127.109...
Connected to gmail-smtp-msa.l.google.com.

I'm running a fedora core 9 server with a firestarter firewall. I have turned off the firewall and the same error persists. I'm also using port forwarding from my router to this server. I have allowed forwarding for port 465 on my router as well.

Can someone please help.

Thanks, Joe
