It may help to note explicitly that spam control includes the possibility to
whitelist known wiki contributors from /some/ filters --e.g. never skip
anti-virus; after all, even known contributors can have their email accounts
hijacked.

Since most email messages are sent in cleartext, it is also worth to note
explicitly the difference in terms of privacy between receiving and collecting.

For sending capabilities, many postmasters end up taking recourse to external
smart hosts because their IP address is in a tainted block, regularly thrown in
the Junk folder by some mailbox providers (e.g. hotmail).  The worthiness of
running a mail queue is lost in that case.
