Hi!
Maybe you've already noticed some spam bots trying to deliver spam to
exactly 100 recipients in one wash up. They take a list of common user
names, add your domain name, and then loop through 100 RCPT TOs per mail.

An escalating delay per RCPT *reject* isn't hard.

Indeed it seems to be related to CNAME chains like in your situation and
