This may be old news, but I've not been in the list for quite some time. At
any rate, is anyone else having issues with Yahoo blocking / deferring
legitimate emails?
My situation is that I host our corporate mx'ers on my network, one of the
companies that we recently purchased has Yahoo hosting their domains mail.
Mail traffic to them is getting temporarily deferred with the "421 4.7.0
[TS01] Messages from xxx.xxx.xxx.xxx temporarily deferred due to user
complaints - 4.16.55.1;
see http://postmaster.yahoo.com/421-ts01.html"
The admin of the facility has contacted Yahoo about this but their response
was for "more information" when they were told that traffic from my mx to
their domain was to being deferred. I may end up just having them migrate
to my systems just to maintain company communications if we can't clear this
up in a timely manner.
