Some versions of MS Exchange are known to do this; I don't remember if it's
currently fixed or not. There may be other NT-based MTAs which also do
this (Lotus?).
Best bet is to find the IP in question, and connect to its SMTP port. If
it's a broken MTA, try to contact its postmaster and encourage them to get
the latest update or patch.
