Hello folks,

Those people checking for valid MX records for a sender's domain from 
within MIMEdefang ... is anybody checking if a sender's one and only MX 
record is a fake MX tempfailing service? Has anyone ever seen this type 
of setup for legitimate e-mail?

For example:

# nslookup -type=MX babe.org

Non-authoritative answer:
babe.org        mail exchanger = 0 mx.fakemx.net.
