Post by Leonardo de SouzaI have the need to create an alias for all User postfix.
AFAIK, there is no shortcut here. You have to do it manually.
Find your aliases file, often /etc/alias or /etc/postfix/alias, and edit it.
Put in a line like:
alluser: tom,dick,harry,etc.
You might or might not find it convenient to include /etc/passwd and then
massage the appropriate entries into the the alluser line.
When you have finished editting, run the newaliases command.
See man aliases for more information.
