Whitelist the servers of the grand-daughter of that retired Chairman of the
Board - and oh - those potential customers of major accounts who put the food on
your table - FIRST.
Then yes. And with a vengeance.
To quote Ken Purdy (out of context..)
'..with method, and foresight, and efficiency.'
94%+ of no-PTR, forged HELO, dynamic-dns arrivals are thorough scoundrels, the
rest ignorant, arrogant, sandalistas, or some combination therof.
So hold-off until acl-smtp_rpct and pull per-user prefs so you can kep at least
one 'if all else fails, email us on..' account per-domain 'receptive.
ELSE keep yer mobile charged and expect to go short on sleep. Or food.
