If you are administering an e-mail server, this is stuff you are 
supposed to know.

If it is a large enough installation to warrant /domain/localpart/ 
naming and MySQL user database, then you really should be fully up to 
speed on this stuff.

In general, your MTA (Postfix in your case) usually receives e-mail by 
SMTP usually via TCP on port 25.

Depending on your MTA configuration it may deliver the mail directly to 
a file itself, or it may send it to another program by means of a 
socket, or by piping the message into another program invoked on a 
per-message basis.

To progress your issue further, you probably need to work out how you 
have Postfix configured.
