[ZendTo] Using the IMAP auth and e-mails don't show up from users' address

[Travis Zimmerman]

I realized I should mention that we are using e-mail addresses to login 
to our ZendTo service to differentiate between our two domains. Don't 
know if that would effect how e-mails are sent. Doesn't seem to be a 
problem for our faculty/staff (AD, username at fsu.edu), just the students 
(IMAP, username at my.fsu.edu).
