My college recently changed its email to google, and rather than using 
smtp.gmail.com for a regular gmail account, it uses the special name that is 
mapped to a google server.

[gccpop]
client = yes
accept = 21995
connect = pop.guamcc.edu:995

[gccsmtp]
client = yes
accept = 21465
connect = smtp.guamcc.edu:465

Perhaps you have a similar set of names you need to use. I have other lines 
for my regular account that uses gmail.
