We do both...but I wouldn't say whitelist like crazy.  More like whitelist
as needed, and find a blacklist or one of the message body parsing utils
you like...or both.

For the rare emergency when a customer (or non-customer) needs to talk to
our NOC and can't get email through, we have these neat things called
telephones.  They work pretty well.  In fact, I think mine often works too
well.
