Well, this is not strange. This postmaster account was automatically created in Exchange Server or SMTP Relay (if you have one). The most important thing is not the sender, but the error message you are getting into this message. Which is?

Lots of things have been said here, but remember, he cant just receive messages from hotmail. Jihad J. Abu-Asab, dont open any port, dont change your proxy configuration. dont do anything else. Start from the basic: are the hotmail users receiving some error message, or the message simply doesnt arrive in your server? If there are error messages, which one are there? Sometimes this is just a problem related to DNS, reverse lookup.

You can do this via an ISP. Contact your ISP. -----Original Message----- From: Jihad J.
