Not a problem

I am using smtp.att.yahoo.com and smtp.gmail.com
Both servers support SSL and alternate ports 465 and 587. The att.yahoo server resolves in the D-Link logs, but fails sending the message.
The Google server reports these two errors:
[WARN] Fri Jun 12 08:39:19 2009 SMTP client failed to send email
[WARN] Fri Jun 12 08:39:19 2009 SMTP failed during sender/recipient dialog
That ATT server only reports back with:
[WARN] Fri Jun 12 02:24:47 2009 SMTP client failed to send email
I'm guessing that the D-Link is having a problem with the SSL part of the conversation. Entourage, Outlook, and Apple Mail all work fine.
