Dear fellow list members,
I just attempted 14 SMTP connections to seperate Yahoo.com MX
machines. 5 failed to allow me to connect, 1 had a "Temporary failure,
try again later", and only 8 succeeded (actually, this figure is
better than my queue would tend to suggest). This is only 14 of the
many many machines which are serving the yahoo.com domain.
In my opinion, the success rate of yahoo.com for mail delivery (note:
I gave up after testing 14 machines, there are way too many, and if my
queue is any indication, the rate will just get worse as I go...) is not
acceptable, both for us as mail administrators with potentially
thousands of e-mails waiting to be delivered, and for their customers
who are expecting mail to be delivered in a timely and reliable
fashion.
I had five immediate failures. To a qmail machine which defers its
mail exponentially, if I tried delivering a single mail to a yahoo
server, it is not beyond doubt to say it could take at least 6 hours
to be delivered with the standard deferral rate and infrequent ALRM
signals.
I am putting forward a proposal that, to help ourselves, our staff,
and the hundreds of thousands of Yahoo Mail patrons, we should contact
Yahoo and pester them to get their system working. These failures are
all too common on their global system, and have been occurring for
months now.
Please give me any feedback, flames, comments, etc, and if they are
personal, direct them to me personally. If they are useful for others
to see (not just for your ego but for general list education about
this problem), post them to the list.
Thanks in advance,
Brett Randall.
