No problem sending to yahoo over the last few days.  Then again, I've
been using gmail and this webmail client most of the time, not my home
postfix server.

The MX for the first one has valid forward and reverse DNS, so that's not
the problem.

This is where you look in /var/log/mail/ on your boxes and see if there
are any strange things being reported for yahoo.  Reproduce them here.
It might also be worthwhile to run a tcpdump on your box, send a short
message to yahoo, and take a look at the tcpdump results with wireshark
or something similar.
