That is not the default behavior.  From sendmail(1), which is the
Postfix to Sendmail compatibility interface:

newaliases
  Initialize the alias database.  If no input  file  is  specified
  (with  the  -oA  option,  see  below), the program processes the
  file(s) specified with the alias_database configuration  parame-
  ter.   If  no alias database type is specified, the program uses
  the type specified with the default_database_type  configuration
  parameter.  This mode of operation is implemented by running the
  postalias(1) command.

% postconf -d | grep '^alias_'
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases

So, the newaliases command should be modifying the alias database in
/etc unless you changed this in your main.cf.  But if that were the
case, Postfix would also *read* for aliases in that non-default
location.  What is the output of the following command on your machine?

% man sendmail | grep Postfix | head -1

That should have been mailwrapper(8).

It sounds like your machine has survived many upgrades of sendmail.  At
one point, /etc/aliases (and /etc/aliases.db) were the common path for
sendmail.  That has since changed to /etc/mail/aliases and
/etc/mail/aliases.db.

Note that /etc/aliases today is a symlink to /etc/mail/aliases.  AFAIK,
this is for "ease of transition".

Absolutely not.  Postfix should not be using /etc/mail **at all**.
If you have your postfix configuration using that directory, you
probably shouldn't have.

The only piece of /etc/mail which is even remotely related to postfix is
/etc/mail/mailer.conf, which tells mailwrapper(1) what actual binaries
to run when using things like "newaliases" in /usr/bin, etc.

The aliases and aliases.db files in a default postfix installation are
in /usr/local/etc/postfix.  As I said, if you've changed these around in
your own postfix configuration, that's your own fault/doing.  :-)

Depending upon what you've done with your own postfix configuration, you
should delete /etc/aliases.db, and ensure /etc/aliases is a symlink to
mail/aliases (e.g. /etc/mail/aliases).

If there's any question about this, re-read what I've written a couple
times; I know that seeing the word "aliases" 50 times in a row can throw
people into confusion (I speak from experience).
