It is not your problem, its yahoo's. If enough people yell at or about
their broken DMARC, maybe they will fix it Their attitude seems to be
that the whole world should be running it. Few others of yahoo's size
are running it, and certainly not the broken yahoo version. FWIW, it did
not cut the spam from yahoo servers by a noticeable amount here. They
have about as many compromised machines as ever. Most of which I send
to /dev/null with mailfilter before fetchmail even sees it. I suspect
they may have in their IT staff, one or more admins that are making side
money by posting spam, and sanitizing the logs immediately.
Thats pretty hard to detect unless you walkin on them in the act.
