New Error Code

Posted by Annalivia Friday, January 8, 2010

Our new MTA is returning a different error code for invalid users now:

ERROR [state=rcpt_to, code=550, text= 5.1.1 : Recipient address rejected: aol.com

Senders using scripts to remove unknown users automatically should be looking for both the new error code and the old one.

The Postmaster site will be updated ASAP. More information on the migration here.

About Me

I'm Annalivia Ford, long time anti-spam expert. I've been in the profession of blocking the bad guys and helping to translate ISP requirements into language that senders can understand for nearly a decade now, though I got into fighting spam as an amateur 13 years ago.

I do not in any way intend to speak for my employer. The content of this blog will be either opinions that are strictly mine, general observations, or information that is already in the public domain.

Have a question? Would you like to give me a job? Or a million dollars to give to Barry? Do you want a cat? You have to want a cat! Email me!

ID YOU FIND A TYPO?? PLEASE TELL ME! I'm serious.


In the banner is one of my dogs, Daisy. If you know me, you'll have heard about her. She keeps me company during work and Together We Fight Crime!!
...or something like that, anyway. Actually, she just thinks SPAM is tasty.
