We are a small company, with some hundreds customers registered for support;
so we chose to protect RT using TMDA http://tmda.net/ . This is an
open-source challenge-response system. This allows us to have a completely
spam-free database. Whenever a new customer does not reply to the challenge,
the mail is delivered by hand; in our configuration, this is an unusual
