Really if I send a mail addressed to same account (email@example.com to) itself it will receive to firstname.lastname@example.org
as well as email@example.com
. This is because the account created in linux machine as abc and sendmail take it as abc for their mailbox.
To prevent this what can I do ? Can I create these mail boxes with the domain name, If it is then Can I get the address as firstname.lastname@example.org
? Is there any other way to prevent this and get two seperate account email@example.com
in sendmail level or POP level ?
