When setting up Postfix, do I need to create a email@example.com
address or just alias this address to an existing user? I suppose this question would also apply to the other standard administrative addresses (i.e. postmaster, abuse, etc...).
I should probably mention that I want ALL email (even email for local user accounts) to go to the virtual mail system. There won't ever be more than 2 or 3 users with a shell account, but I don't want even their mail accessed that way. ALL mail should be sent & retrieved via an MUA (Thunderbird, etc...) using the vitual system built from:
Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Fedora 13 x86_64)
