FYI ASTA and some other initiatives evolved into MAAWG, the Messaging Anti Abuse Working Group (http://www.maawg.org)

There are far more best practice documents available now - http://www.maawg.org/about/publishedDocuments

Some of them are focused on outbound spam, some on efficient abuse desk management etc. And there's the MAAWG sender BCP for email marketers - developed jointly by ISP and email marketer / bulk email sender members of MAAWG.

The list of documents so far are:

* Trust in Email Begins with Authentication (MAAWG Email Authentication White Paper)
* Abuse Desk Common Practices
* MAAWG Best Practices for the Use of a Walled Garden
* MAAWG Sender BCP Version 1.1 and MAAWG Sender BCP Executive Summary
* BIAC-MAAWG Best Practices Expansion Document* Anti-Phishing Best Practices for ISPs and Mailbox Providers
* MAAWG - Managing Port25
* SPF and/or Sender ID
* Code of Conduct
* Email Metrics Reports

Thanks Suresh. Didn't know that. Do now.
