Question : hotmail is blocking IP

we were fine sending email to hotmail. but today i realized , hotmail is rejecting our email address.

I hve checked with dnsstuff , its not listed any  spam database, its clear.

Some one said to check http://ipremoval.sms.symantec.com/, and its blocked by this site

this small busienss server, and my server is not open realy.

so what i am trying to do is : checking all pc for spyware or others

but does any one have same problem with hotmail ??

my domain is receving by gmail,yahoo .

only hotmail is giving trouble.
please advise.

Answer : hotmail is blocking IP

Hi,

I think you got to look for SPF record. Goto http://www.mxtoolbox.com/spf.aspx  and verify your SPF record

Create SPF Record:

• http://www.microsoft.com/mscorp/safety/content/technologies/senderid/wizard/ 
• http://www.openspf.org/ 

That should help

Thanks
