Go daddy mail services admin

GoDaddy never was that large of a problem..maybe things have changed in
the passed few months? Every now and then they would do a /24 listing
but usually removed it fairly easily. Maybe it wasn't noticeable in the
environment that my old company had setup. 2.5million emails sent to a
load balancer which sent to 1 of 8 outbound spam filtering gateways that
rotated through a pool of ips once an hour (5ip's each). So if an IP was
blacklisted usually we would get the complaint, take it out of rotation,
and contact the party to find out why it was listed and take action to
correct it. Or we will see one hour the queue gets huge and take a look
at the emails that are sitting in the queue...if they are mostly
directed at yahoo/Comcast/godaddy then they are likely blocking that IP
address...

Yahoo is tougher to get a hold of that's for sure...they use a different
type of anti-spam system (not that I'm saying its really effective) that
prioritizing / deprioritizing senders emails. At my old company I had
dedicated/colo customer's setup domain keys, spf records, rDNS, and set
their retry times to be short intervals at first then progressively
longer ones so they retry for about two days. I found that over several
days (if you aren't sending spam) the reputation seemed to start getting
better and your emails were being delivered without 'depriortization'
(which is those annoying 451 Message temporarily deferred notices).

Now if you have a system where 360,000 pop3 users send mail through your
network, generating about 2-2.5million emails a day, then a lot of those
are likely towards Yahoo!. Make sure to separate forwarded mail (into
your users inbox and then auto forwarded to user at freemail.com) from your
customers manually sent emails. In some servers it is not really
possible, so run some reports through the logs to find out who the top
10 recipients at yahoo is for a few days. Those are likely the ones
receiving the spam and causing your system to have problems. Grep
through your logs and find out who those emails were originally sent to
and then forwarded & fix. Yahoo doesn't tell the difference between
spam/forwarded spam :)

Alternatively google around...the director of Anti-Spam at Yahoo has his
email address on some mailing lists and posts to them....he's actually
responsive (2days ish) and quite helpful (me != proxy). There are also
several yahoo employees on nanog who are also tired of the issues
sending email to Yahoo and can get some stuff done.

|GoDaddy is about as worthless of a mail provider and it gets.  I can't

I would add that Yahoo email should also be on that list of email
providers to tell one's customers to avoid, for all the reasons
mentioned above.  Yahoo's email is especially bad around the area I live
because the local DSL provider uses a re-branded Yahoo email service.
It has become easier for me to walk to my neighbor's house and
hand-deliver a letter, than to try sending an email to that neighbor's
Yahoo email inbox.
