IMAPx - no. However this is a mail user agent issue and qmail is a
mail transport agent. There are patches to the UW imapd that allow it
to support qmail's Maildir/ format. There is also Courier IMAP which
is a separate imap deamon that supports Maildir/ format. Look for
pointers to these on http://www.qmail.org
LDAP - no. Andre Oppermann has some ldap patches for qmail. See
http://www.nrg4u.com
MIME - Not a qmail issue. qmail doesn't care what is in the body of
the message. It will support the 8BITMIME SMTP protocol extensions.

No mailing system does! Some can help you minimise spam but NOTHING
(apart from social change and re-education) will eliminate it. That
said, qmail has a number of mechanisms to help you deal with spam. You
can prevent specific senders and sender domains from talking to
qmail-smtpd. You can prevent unauthorised mail relaying. If you use
Dan's ucspi-tcp package to control the execution of qmail-smtpd
(recommended)_ then you can use the rblsmtpd program in that package
to block mail from sites listed with RBL, ORBS, DUL etc.

Incoming, outgoing, mailbox storage? What limits do you have in mind?
Basically, no. There are quota patches for qmail. The user quotas
problem is not really the job of the MTA. There is a mechanism to
limit the size of incoming mail messages but it does not work on a user
level.
