+**** Setting up the MDA

+# The choice of deliver from dovecot for MDA was based on the support for the
+# mailsieve filter language, which is a nice DSL and has plugin support in
+# roundcube. maildrop lacks this support.
+
+# squeeze has dovecot-1.2. upgrade notes:
+# - we might want to upgrade to their sieve (instead of cmusieve)
+# - we want to add the -s flag to deliver in master.cf
