Joe Job

[bellgamin]

Two of my domains are presently undergoing Joe Job attacks (http://en.wikipedia.org/wiki/Joe_job) against their catch-all email accounts.

The usual way to handle JJ's is to disable the domain's catch-all email account and "blackhole" them (set them to "fail: no such address here").

For various reasons, I am trying to find a solution OTHER THAN the blackhole approach. Any suggestions would be greatly appreciated.

Hmmm... it seems there are no Webmasters around Wilders at this time. Or else I am the only WM who has ever been hit by a Joe Job. :-\

@Cudni - MUCH thanks. I am looking into Sender Policy Framework as a possible solution.
