    If I have a domain name for which there are 3 MXs setup in a Round 
Robin configuration, wouldn't mailman be given a different IP each 
time?  For example:

; zone file fragment
@     IN MX 10 mail.example.com.
mail  IN A
      IN A
      IN A

    If I tell mailman SMTPHOST='mail.example.com', in theory it should 
receive a different IP to connect to each time it queries that host 
name.  UNLESS mailman is internally caching that information (to use 
again on subsequent runs.)
