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

[Jules Field]

Travis,

If the students enter their entire email address (username at my.fsu.edu) 
into the ZendTo login "username" box, then set
     'authIMAPDomain' => '',
in preferences.php.

If they just enter their username, then something more subtle is 
happening which I will need to investigate further.

Please let me know if that helps.

Cheers,
Jules.
