Unable to send Email to a Hotmail Account from MS Exchange 2003

[ohdayes]

Hello guys i need your help desperately.

I setup my Exchange 2003 Ent on Windows server 2k3 Ent

I am able to send emails to "everywhere" except hotmail.com. I can recv email from my hotmail account and if i reply to the email it will come to my hotmail account, but if i create a new email and send it to my hotmail account it will get lost in space.

What do i do?

p.s. i recently followed kb article# 817379 to fix a mobile messaging issue but if my memory serves me right, this issue started before i did that.

Do you have a reverse DNS record for your mail server? (Setup by your ISP on their DNS server)

 

[ohdayes]

yes it points to the isp's name not the server name. but it used to work before with the same settings

Are your test messages still in the Queue or have they gone out?

Another possibility is that they (Hotmail) have blacklisted you. Have you checked the online RBLs to see if you're listed?

The Queus are all empty.

Which website should i go to check the RBLs ?

Dont worry guys thanks for your help, I just tested it and it started working fine again. Thanks again

For future reference...
An RBL is a Real-Time Block List. There are several online that are very good (and free).

Also, if you haven't configured your Exchange server to take advantage of RBLs to eliminate some of the spam coming to your server, you should. It can signifcantly help fight the battle against spam.

To set up your server to use RBLs see the link below:

Note: you can use more than one. I use ORDB.ORG, SPAMCOP.NET, and SPAMHAUS.ORG

Hello ohdayes;
Could you tell me how you have repaired your Exchange's server?
I'm with the same problem than you.

I am able to send emails to "everywhere" except hotmail.com. I can recv email from my hotmail account and if i reply to the email it will come to my hotmail account, but if i create a new email and send it to my hotmail account it will get lost in space.

And I don't know how to solve it. Could you help me,please?
I have tried everything and nothing solve it.
Thanks.
