Kevin -

We have a single, unshared server. We do no mailings at all - none.  We've
got SPF setup, an abuse address, postmaster gets read, etc. The only email
we send to Yahoo! is single, non-automated messages from a human here to one
of our vendors and one of our salesmen.

It has become damn near impossible to get an email through to Yahoo.  I have
filled out their damn forms a half-dozen times.  No response, no help at

We have advised our vendor - and instructed our employee - to quit using
Yahoo.  There is, unfortunately, no other solution.  They don't listen, they
don't respond, and they don't care.
