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).
