SendMail wont send anything to Hotmail or Yahoo Users.


I have sendmail version: 8.13.4
I have the only modification I can remember doing is:
MASQUERADE_AS(`ipalaces.org')dnl

I can send emails perfectly to gmail accounts. Here is a sucessfull output of an email send to gmail:

This is a test of the body.

I originally thought the reason hotmail or yahoo didn't receive my emails was because I had no reverse DNS for the IP I was sending the emails out with. Therefore I had my VPS provider create one for my IP. It now reflects ipalaces.org with the IP I use to send out emails (64.74.153.24)

Even after the reverse DNS in place, hotmail nor yahoo could recieve my emails. I am now pretty much stump as to why. I have googled and scanned various other solutions and I havent found anything.

Here is a verbose output of using sendmail to an hotmail address of mine:

The main thing that strikes out to me is that hotmail says "Queued mail for delivery" whereas Gmail normally says "OKAY". It seems as hotmail gets the email, and then decides it's no good. I don't know if my IP is blacklisted or I have to change something in my configuration from 127.0.0.1 to my IP, or what I have to do.
Our team has been researching this and some answers would be much appreciated. Thanks.

I believe that Hotmail and Yahoo now want you to have an SPF record in DNS before they'll take your mail.

An update: Yahoo now works.
Hotmail does not.

I even followed the exact SPF records as MSN postmaster recommends.
