Blowback sucks

I hate blowback. Or call it backscatter, or outscatter, if you prefer. Either way, it's no fun.

If your mail server sends it, you're contributing to a growing problem.

I don't know what's worse:

1. All the blocked messages from the poorly designed Barracuda anti-spam filtering devices out there in the wild. (Accept-then-reject spam filtering is so 1998.)
   
   
2. All the random "Confirm your YahooGroups signup request" emails. (Allowing email signup requests to be originated via email is so 1998.)
   
   
3. All the rest of it I get (bounces from spams forging my domains, etc.).

Actually, I do know which is worse. Consider that list ranked in order of my personal annoyance.
