Log Message:
Update mail/courier-imap to 4.1.0.  Changes from version 4.0.6 include:

  + Install some more of the HTML documentation in the location expected
    by courier-mta.

  + Moved the default locations for the imapd and pop3d SSL certificates
    into ${PKG_SYSCONFDIR}.  These paths may be changed directly in the
    imapd-ssl and pop3d-ssl configuration files by modifying TLS_CERTFILE.

  * New capability to control announcements of IMAP ACL support when
    starting imapd.

  * Optimization: Skip going through the motions of outputting the results
    of a SORT if the number of sorted messages is 0.

  * Have CREATE and RENAME also create courierimapuidlist.

  * Log total bytes sent/received in IMAP and POP3 sessions.
