    I can receive email from hotmail but I cannot send, however if I reply the email I receive from hotmail it will be delivered to hotmail. It seem there is a problem with the way I am sending the email B/C when I reply the email it will be delivered, and this happen with hotmail only.

    Any help would be much appreciated.

    Is this related to Exchange? I have moved the question to the Exchange forum, but it it's not, I will move it to the Misc forum.

      I'm not so sure that he's on an Exchange server...but I did notice that Hotmail recently boosted their email filtering and some of my clients with SB servers can't send to hotmail addresses now.

        Hello Dear,
        You are facing same problem like we had 2 months ago. We Installed Exchange 2003 on windows 2003 server OS and setted up every thing. We were sending email to almost every address but didn't able to send on hotmail. We called to our domain hosting company for reverse lookup. Now we can send any receive email on hotmail.
