Been there, done that, as have others.  Either there is no postmaster
@{,lists.} or they are filtering and/or ignoring questions
about the constant spam being sent to all freebsd lists.

It does though. Legitimate list messages are blocked when list member's
MTAs reject spam sent via a list and the Mailman list
software subsequently suspends the subscription.  This can happen to
anyone subscribed to more than one list.

Why does not follow standard practice of moderating mail
from non-members is the question we should be asking.  It's not like
this takes any real effort or like there have not been several
volunteers.  Mailman also allows for moderation of new members.  Given
that spammers and bots can and do subscribe and trojans do parse
addressbooks it is both unprofessional and reflects poorly on all
freebsd maintainers that's postmaster / Mainman maintainer
does not follow this standard practice either.  Finally, any MTA not
using zen.spamhaus, spamassassin, dcc, razor, pyzor et al is not, by
definition, properly configured.

Claims that 'it tends to come in bursts, but really isn't that much' or
'having a subscriber only policy doesn't necessarily prevent spam' tend
to indicate the claimant knows little about list moderation or spam
filter or has a vested interest in UCE.
