[members-discuss] Filtering issue in 128/8

Based on my experiences, live.com (Hotmail) is one of the most
difficult destinations to deliver email to. Despite following every
single guideline they publish, our mail was routinely marked as spam.
I think your problems are probably not related to the netblock you're
using, but instead are related to Microsoft's over-aggressive spam
filters.

What we eventually did, on many peoples' recommendation, was to sign
up with a "reputation service", like ReturnPath
(http://www.returnpath.com/). For a fee, they will tell Microsoft that
you're good people, and not spammers (yes, that's really all that they
do, but it works). Is it corrupt? Yes, probably. But that seems to be
the price to pay if you want to deliver mail to Hotmail, as nothing
else we've tried seemed to help.

Good luck!
