i create one smtp connector and allow send and receive mails to all domain.that means no restriction on any mailbox. but the problem is that my all mailbox enabled users are able to send mail to any domain like yahoomail,gmail,hotmail but thay are not able to receivemail from any domain accept my own exchange doamin. means if they send mail to hotmail id. the mail sent successfully..when when some body replied them mail will not come from any domain. i m not deployed any restriction over any mailbox. can any body help me out to trace this problem.
