First off, make sure Postfix is looking for the alias files where you THINK they are looking.  Use the 'postconf' command to make 
sure it's looking in the right place.  For example:

> [root at mail1 root]# postconf alias_maps
> alias_maps = hash:/etc/postfix/aliases
> [root at mail1 root]# postconf alias_database
> alias_database = hash:/etc/postfix/aliases

If both of these aren't pointing to your aliases file in /etc, you can change them to do so using postconf:

postconf -e "alias_maps = hash:/etc/aliases"
postconf -e "alias_database = hash:/etc/aliases"

Then run 'newaliases' to rebuild the aliases.db file from the text file.

Hope that helps!
