ohh.. it appears that "aliases" is for local users. So if i need to use this file (/etc/aliases) to forward to the "outside world" i need to use "virtual" file as pointed out here

... actually... the prehistoric times "~/.forward" solution still works great.

Gents,
 what is the difference between /etc/aliases and /etc/postfix/generic ? and why aliases is been ignored by postfix despite main.cf having:
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
entries enabled?

i have root:[log in to unmask] in aliases, but maillog is clearly not happy with it....
