A customer led me to the same block. Unfortunately they were some very
important emails and the customer was more than a little irate.
We are a semi-high volume site with plenty of people who expect to receive
hotmail mail, so this is REALLY BAD. I cringe at the thought of making a MTA
top-level whitelist entry for all the hotmail IPs that I can find, or of
removing sorbs from our list of postfix RBLs.
We removed sorbs. I don't think it's even open for debate at the current point.
If places like hotmail mx's end up on the blacklist you *will* have upset
customers.
I also don't much care for the idea of using Sorbs only to tally points in
SA, since we get so much crap, we'd like to reject most of the obvious stuff
out of the gate - otherwise I envision our hard drives filling up twice as
fast with crap nobody wants anyway.
Look at other rbl's, consider some or all of:
abuse.rfc-ignorant.org
dsn.rfc-ignorant.org
list.dsbl.org
sbl-xbl.spamhaus.org
opm.blitzed.org
It sucks that microsoft can just do whatever they want since they have sooo
many users, but as this is the current state of our reality, I am interested
in what people are doing to deal with it as is.
Removed sorbs, no choice.
Is this causing anyone else problems?
Yep.
