Ah yes, mailing lists. I would whitelist (in advance) all my current
lists emails and other correspondents. Also, mapSoN is (allegedly)
smart enough to recognize if the incoming email is in reply to an email
that I sent. In that case, it automatically white-lists the sender.
Yes, white listing the entire domain is risky... although if it's a
problem I'm sure I'll find out ASAP.
Thanks,
Eric
P.S. Why did you choose Drupal over say Mambo Server or Joomla! I ask
because I want to use a CMS for a couple of upcoming projects and Drupal
seems really good and quite popular... but so does Joomla! I even looked
at Typo3 but gave up when it simply would not run. It's probably an
Apache config option about following sym-links but I'll be damned if I
could correct it!
