extent of IMAP support?

[Chris Cutler]

Hi,

I was wondering what the extent of the IMAP support in mutt is.  I was
at www.imap.org looking at their product database and mutt is listed
as having IMAP support without giving any specifics (IMAP4, IMAP4rev1,
IMAP2bis etc.)  Can anyone give me more details about what mutt does
and doesn't have implemented and whether it officially supports IMAP4?

Thanks.
