>Description:
Using mail/mutt-devel and security/cy2-digestmd5 from HEAD pkgsrc,
recalling a postponed message using Mutt's `recall-message' function
fails when authenticating with DIGEST-MD5 to an IMAP server. This
problem is explained in more detail as Mutt PR 2034:

http://bugs.mutt.org/cgi-bin/gnatsweb.pl?database=mutt&cmd=view+audit-trail&pr=2034

>How-To-Repeat:
Authenticate with DIGEST-MD5 to an IMAP server and postpone a message.
Type `R' (or whatever key `recall-message' is bound to) to recall the
message. See Mutt fail.

>Fix:
This problem is fixed on Mutt's CVS HEAD. The patch is attached and
available from
http://salmi.ch/~jukka/patches/pkgsrc/localpatches/mail/mutt-devel/patch-sasl-digest-md5
