Hi all,

I don't think I've seen any chatter about this on the list. If I missed it, I 
apologize.
In the wild today, from AOL, there is this:

521 5.2.1 :  (DMARC) This message failed DMARC Evaluation and is being refused 
due to provided DMARC Policy

This has a SMTP status code that is meant for an initial connection. See 
http://tools.ietf.org/html/rfc1846.
The extended SMTP code is meant for disabled mailboxes, which I suppose one 
could stretch to fit dmarc, but that seems wrong too.

This doesn’t seem right to me for using with DMARC. AOL uses 521 for other 
anti-spam purposes as well. Has there been discussion about appropriate SMTP 
responses?
