I tried it with brackets and still get the same error. I can ping the mailman server from the mailserver (nkuaxp.nku.edu). In the error it strips off the brackets.
From nkuaxp: Sending failed: Message sending failed since the following recipients were rejected by the server: [EMAIL PROTECTED] (The server responded: "5.1.2 unknown host or domain: [EMAIL PROTECTED]") From exchange 5.5 server Sending failed: Message sending failed since the following recipients were rejected by the server: [EMAIL PROTECTED] (The server responded: "Relaying is prohibited") the address in the To: field was [EMAIL PROTECTED] for both. Sendmail is being used on the mailman server. I don't understand why the exchange server would say that relaying is prohibited. Is this a problem on the mailman server. If so what do i need to do to fix it.
