Drastic method. You likely "fixed" the problem by causing newaliases to
be run.

That is not a rancid question. It is 100% an email question.

Seeing as it's coming up often nowadays, I'll answer it.

Rancid does not find any mail server at all. It composes the mail and
hands it over to the local MTA (mail transfer agent) which in your case
is Postfix. Rancid's job is to compose a mail, Postfix's job is to get
that mail delivered.

Postfix looks up the MX records of the *domain* in each mail address,
and tries to deliver the mails to each server in that list in turn using
SMTP. How it does this is fully described in many quality articles on
the internet.

http://www.postfix.org has excellent documentation on all aspects of SMTP
