AOL Error Code Question

Hey folks. I have started working with some AOL data. I have one IP that seems to be doing well 60,000 messages per day 6-8% open rate. I have a few others though that are giving me this error message:

status=bounced (host mailin-02.mx.aol.com[] said: 521 5.2.1 : (CON:B1) http://postmaster.info.aol.com/errors/554conb1.html (in reply to end of DATA command))

Is this a 554 CON:B1 error or a 521 CON:B1 error? If its a 521, this isn't an error code published on their web page. Either way how should I handle this? Do I pause sending for 4 hours, etc.?

One of my IPs has a neutral reputation based on AOL's ip reputation tool but still gets this error every time I try to send.

My sending volume is just under 100 per hour per ip for warm ups.

Thanks in advance for any assistance.

Abe

 

Reputation tool is a known honeypot.

You are not alone:

Not that others having the same problem as you is particularly comforting..

 

Thanks for the reply. I went ahead and posted a question to the AOL blog (comment #12) and put in an email to support. Probably won't get a response but who knows.
