Hi There, I just did that and the mail did not arrive again. However, I did some more tests and it looks that reply mails arrive back to hotmail. So the situation is: my postfix->hotmail = do not arrive hotmail->my postfix->hotmail = arrives to both my postfix and hotmail too.

Create a correct SPF record, and ask if Hotmail (MSN) will add your domain to the 'Sender Policy Framework' (a.k.a. Sender ID Framework) For more info you can do a search on the forum for 'Hotmail' you can also read this: http://postmaster.live.com/FAQ.aspx and this: http://www.microsoft.com/mscorp/safety/technologies/senderid/default.mspx Please note that it's not only Hotmail that you will have a problem with. Yahoo, and many more do also have something like this.
Fix spf! I fixed spf and others providers received emails, i added a domain, i will wait for adjusts (in SENDERID). If problem persists, i will be back... Thanks!
