I have postfix configured with a relay thru my ISP server, however because some problems of my ISP the mails to the MSN domains (Hotmail.com, Live.com, msn.com) are refused, My ISP said that we should configure our mail server so the mails to those domains do not go thru the relay. How can I do that? Thank you in advance
Ok, then it should be no problem to just remove the relay settings in postfix main.cf and send emails directly. Nevertehless you should check your IP address first if it is not blacklisted: http://www.mxtoolbox.com/blacklists.aspx And you should make sure that a reverse DNS entry exists for your IP address that points to the hostname of your server.
Till, thanks for your help, but my Static IP it is blacklisted, that is why we started to use the ISP relay (Itwas easy for the ISP to use a relay than de-list all the IP address that are blacklisted), Is there a way that only the mails going to Hotmail.com, Live.com, msn.com go thru theserver and the rest go thru the relay?
