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

[Travis Zimmerman]

I tried to use my university's AD for the students (there is a previous 
e-mail I sent to the ZendTo mailing list about a week ago), but due to 
how our Microsoft Admins configured it they needed to use an alternate 
attribute.

Yes. When I login to LDAP or AD and drop off a file, the e-mail sent to 
the recipient will show my e-mail address in the From field. If I login 
using the IMAP auth the From field lists the servers default e-mail from 
zendto.conf and the Reply-To field has the IMAP account's e-mail address.
