Postfix aliases

Hi. I’m trying to set postfix to look for aliases in an aliases file under my /home/user directory. The instructions I’m using tell me to edit Postfix’s “” file, but that’s certainly not possible!

How can I point to this file for mail coming in under a particular domain? I’ll be happy to have all inbound mail on this domain find its ultimate destination through this alternative file.

From my instructions, this is what I’m supposed to put in Postfix’s

alias_maps = hash:/etc/postfix/aliases,

Thanks in advance.
