Yahoo have a few issues, and i commented out the postscreen stuff to get an yahoo mail. Then an onslaught of crap came in.
If yahoo cannot send email as it is poorly configured with no mx, high ports (port 25 is down a bit) then postscreen is worth its weight in gold
Postscreen is essential, yahoo email is err in need of some help.
Twelve hours later* and said email come through. Sort of makes the physical post office seem fast. Mind that is probably this guys fault (my blog).
If you have yahoo mail – you have issues
* a sign of problems
