When I want to send an e-mail, I get this error message, we have no outbond control sending mail. Can anyone help me?
Error transferring to mail.XXX.com; SMTP Protocol Returned a Permanent Error 554 banuo@XXX.com.tr: Relay access denied
Subject: Relay access denied??
That is related to the SMTP-Outbound-Controls tab of a Configuration document. Basically you have prevented outbound spoofing on your server (which is a good thing). Apparently you have it set to not allow sending e-mail with a return address of XXX.com.tr. In other words, if your domain is ABC.com.tr, you should not allow your users to send mail from XYZ.com.tr.
You might also search for spoofing or open relay in this forum or on Google.
