One of my customers had :fail: no such address set up as their default address. Some SPAMMER decided to bomb his domain with every possible [email protected]_domain.name This caused hundreds of failed address messages to return to sender. The senders were all phony yahoo addressess...
I love it, if you have several web servers, you are supposed to watch your logs for too many yahoo bounces, what world do they live in?
Just curious if anyone had this before. AOL is a dream to deal with compared...l
Well that is what is weird, it should reject invalid emails, and I am not sure why those were showing as existing if they did not... The server logs show all the server is rejecting invalid emails...
Very strange, and I am not sure what to make of it In either case I am hoping that they will want to work this out with me. Every customer I ever had that had to deal with yahoo support has gone through hell, or so they tell me. I fear the same is about to begin but for me
Exim in a cPanel system, since it allows "catch-all" and lets the user configure whether to fail or blackhole the mail, accepts the mail before determining what do with it, as long as the domain exists on that machine. (Exim might do this in general, too, but I don't generally use it, so not as familiar with it). It's why I generally recommend :blackhole: instead of :fail: in almost all cases.
It's a risk you run with any mail system that does this, since sendors can so easily be spoofed.
