If exim -bt "*[email protected]" says it can route the message, it will be accepted as that is a valid email address. As to why it might be accepting it: Domain has a catchall meaning that <anything-valid>@example.com will be accepted by the server. Otherwise, it's up to whatever conditions you have on the router being used. Make sure that "*" isn't being treated as a wildcard by some strange lookup. Apparently LDAP special characters as "#", ",", "+", """, "\", "<", ">", or ";". To get exim to tell you exactly what it's doing, try "exim -d+all -bt "*[email protected]"". If you can't see why it's behaving like that, you may have to post more. Is this _really_ you? Domain Name: MYDOMAIN.COM Registrar: MYDOMAIN, INC.
