Well, I thought that was the best way to eliminate spam ... better than
telling the spammers that the users don't exist.

With sendmail I have been running that way for years.

Indeed the postfix man page for aliases(5) says:

/file/name
Mail is appended to /file/name. See local(8) for
details of delivery to file. Delivery is not lim-
ited to regular files. For example, to dispose of
unwanted mail, deflect it to /dev/null.

That is undesirable behavior.

jane has a local unix email account, but does not have a valid email
account within mydomain.com

She should only receive mail sent to 'jane@otherdomain.com', not mail sen=
t
to 'jane@mydomain.com'

Unfortunately, I thought that I *was* following the textbook example.

The 'virtual' man pages do not mention anything about the local domains.
And since I was migrating from the sendmail virtusertable I (mistakenly)
assumed that they were functionally equivalent.

The functionality of the aliases file is not the same as virtual.

Q: How do I do a domain-wide 'catch all' of mydomain.com within the
aliases file? The equivalent of:

@mydomain.com catchall
