I've also opened a debian bug report:

http://bugs.debian.org/384076
> Environment:
Debian Release: 3.1
Architecture: i386 (i686)
Kernel: Linux 2.6.16-2-686
Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8)
> Description:
Running mutt against Mirapoint IMAP4PROXY 3.5.8-GR server, the server gives the \
following capabilities before login:

CAPABILITY IMAP4 IMAP4rev1 ACL QUOTA LITERAL+ NAMESPACE UIDPLUS

However, after login if mutt would check, the following capabilities would be \
returned instead:

CAPABILITY IMAP4 IMAP4rev1 IDLE LOGIN-REFERRALS MAILBOX-REFERRALS
NAMESPACE LITERAL+ UIDPLUS CHILDREN

Note that ACL is no longer in the list after login.

It seems to be within the spirit of the rfcs, to recheck after login...here is a \
small patch to mutt 1.5.13 that will re-ask the capabilities after authentication.
> How-To-Repeat:
Here is the debug output before applying the attached patch.  Note that the server \
doesn't know about MYRIGHTS.  Mutt would know this and not ask, if it had re-checked \
capabilities after login:
