My mail server has a primary domain example.com
I have users that have old email addresses such as users@???, and
example3.com. I want to accept email for example2.com and forward the
email to the user@???
I have an alias list such as
------
user@??? localuser
anotheruser@??? localuser2
-----
I also want to have a global alias list for postmaster, info, and abuse
i.e.
-------
postmaster: localuser
abuse: anotherlocaluser
-------
How can I have multiple alias lists with different formats.
