I like 'em short and sweet. From our two incoming mail servers:
MX1:
----
220-Please leave a message. However, you have the right to remain
silent.
220 Everything you say will be recorded and will be used by us.
MX2:
----
220-Kemosabe no in tipi now. You leave um message after little
smoke signal
220 and Kemosabe get back for pow-wow real fast.
Hey, I never said they were *valid* responses, but it's a response
no less. I don't like to advertise what version of mailer we're using,
so I changed it all.
