Try one of these threads... lots of good debugging hints.

For instance, have you tried using a telnet connection to gmail smtp port and send it commands by hand?

eg. > telnet smtp.gmail.com 25

results in

Code:

telnet smtp.gmail.com 25
Trying 64.233.185.111...
Connected to gmail-smtp.l.google.com.
Escape character is '^]'.
220 mx.google.com ESMTP hsfkjs47g

also, see this gmail page: http://mail.google.com/support/bin/answe...swer=13287

keep trying.
