bring loop detection support. we handle this with a qmail-like approach which
consists of checking headers for a custom header, but we also count how many
hops the mail went through and use a hard limit (currently set to 100 as was
recommanded by RFC) as a safe-guard.
idea discussed with jacekm@, qmail approach suggested by claudio@ a long time
ago
