I have sendmail servicing multiple domains successfully.
For the first time today and email arrived for firstname.lastname@example.org
Where domain.com is one of my virtual hosting domains.
Since adm is in my aliases list as a default entry the email was rerouted to me the system administrator instead of being bounced back as an unknown user. This occurs for all those default aliases in /etc/aliases
How can I change this to work correctly? or atleast how I think it should work!
