I have iRedMail Free and I'm trying to add email@example.com as an alias of firstname.lastname@example.org. I followed this guide http://www.iredmail.org/wiki/index.php? … pLDAPadmin but when I send to my alias from an outside email address, I get an error notice that says email@example.com is an invalid host/domain. I've tried two different outside email addresses. I checked my DNS and everything works. Do I need to add anything to Postfix config?
Please let me know. I greatly appreciate any assistance.
P.S. Alias config via LDAP is attached.
