Most likely.

If so, and if your aliases are in /etc/aliases, after setting
up postfix, run

postalias /etc/aliases

Have a look at /etc/postfix/main.cf, looking for the alias_maps
parameter.  On our list server, this looks like:

alias_maps = hash:/etc/aliases
because I find it convenient to keep our mailman aliases in a
separate file.  After changing that,

postalias /etc/aliases.d/mailman

Some distributions may place Postfix's default alias file in
/etc/postfix/aliases.  If so, you can either copy your aliases
file, or change the alias_maps parameter.
