- 421 CON:B2
http://postmaster.info.aol.com/errors/421conb2.html
EXPLANATION:
The IP address you are sending from has been blocked due to unfavorable e-mail statistics. The error message generated is a 421, or a temporary refusal.
SOLUTION:
Number of Complaints:
When an AOL member clicks "this is spam" for a piece of email sent from one of your IPs, this is considered a "complaint". If you are having difficulty with the number of complaints you are receiving, a feedback loop would benefit you. Once you have requested a feedback loop you will be notified when a member clicks "this is spam". See feedback loop for additional information.
Bounce Message:
America Online requires bounced messages be kept at a minimum. It is also required that a large part of these bounced messages be accepted by a party responsible for the sending MTA.
