[web2py] Cannot send email using IMAP server.

[Aris Green]

I am using mail.send and I get messages like the follow: 
WARNING:web2py:Mail.send failure:(-1, 'IMAP4rev1 SmarterMail').  Can I use 
web2py tools.mail to send messages or do I need another Python library to 
send the mail.  The settins are similar to this:

mail.settings.server = 'mail.foo.com:143'
mail.settings.sender = 'foo....@foo.com'
mail.settings.login = 'foo....@foo.com:FooPassword'

What magic settings do I need?  

Thanks
