Not sending mail to hotmail, yahoo, etc
Isaias Formacio
can't seem to find it, I hope someone here can help.
I administer 2 companies, on both they have Exchange 2003, one of them works
perfectly, the other does not sends email to any hotmail, msn or yahoo (and
I guess some other domains) accounts... The email seems to have left the
server perfectly, I have even sent a test email using telnet from the
failing server and everything looks alrigth, does anyone have a clue on what
could be happening?

Have you tried manually establishing connection to Yahoo/Hotmail/MSN's SMTP
ports and sending a message that way. It might give you a clue.

AOL and a lot of other ISPs have started rejecting mail from a lot of
servers in an effort to stop spam. Some reasons for being blocked would be -
Your SMTP server has no reverse lookup records (PTR)
Your IP is considered to be on a dialup or dynamic IP [1]
Your IP or SMTP server has been blacklisted as an open relay
For the reverse lookup, check out your domain at www.dnsreport.com; ask your
ISP to create the record for you, presuming you have a static IP.
If you don't have a static IP, you can set up an SMTP connector that points
to your ISP's SMTP server & add hotmail.com, aol.com, etc. there...

Nope, No NDR. I sent the first messages 3 days ago and I have not even
recieved a delay message or something.

Yes, that's what I did with telnet, Hotmail did not seem to reject the
email. I've posted the SMTP conversation from the failing server in my first
post.

that if my IP is on a Spam List it would not recieve it, will it? And I
would get a message telling me that (my IP is on a black list), right? I've
seen those messages for black lists.
What I see is, Hotmail recieves mails from both of my servers, but it only
delivers messages to their destination from one of them unless it's a
reply...
Can I do some sort of bridge from my hotmail hated server passing through my
hotmail loved server for delivering the hotmail,msn,aol,yahoo messages?
Do you think this workaround would work?
Any other clue???
