[imp] How to list mailboxes in a faster way

[Ángel Galindo Muñoz]

	Hi!

	We've found a different behaviour in how IMP lists the mails in our
mailboxes against Sun Messaging Server and against MS Exchange. The
exact versions are:

- Sun Java(tm) System Messaging Server 6.3-6
- Microsoft Exchange Server 2003 version 6.5.7226.0
- Horde 3.3.5 and IMP H3 (4.3.5)


	When IMP tries to list the mails on Messaging Server it does it this
way over IMAP :

00000008 FETCH 1:20 UID

	and when IMP tries to list the mails on Exchange it does it this way
over IMAP :

00000008 FETCH 1:20 (UID ENVELOPE BODY.PEEK[HEADER.FIELDS (Newsgroups
Content-MD5 Content-Disposition Content-Language Content-Location
Followup-To References)] INTERNALDATE RFC822.SIZE FLAGS)


	As IMP demands more details for each mail, this request becomes
painfully long for mailboxes with lots of mails.

	How can IMP be configured to send simpler requests to Exchange although
having different capabilities? Thanks in advance!
