We're attempting to use a sendmail script from the website to email a user who's email address is the same of the site (www.domain1.com
). However, when we attempt to send email to this user, we get the follownig message:
The Postfix program
<email@example.com>: unknown user: "joe"
Reporting-MTA: dns; server1.example.com
X-Postfix-Sender: rfc822; firstname.lastname@example.org
Arrival-Date: Mon, 5 Nov 2007 17:03:55 -0500 (EST)
Final-Recipient: rfc822; email@example.com
Diagnostic-Code: X-Postfix; unknown user: "joe"
I know this is because Postfix thinks the domain is local to the server but how can I tell postfix that this particular domain's email server resides externally?
