Quoting te...@cnysupport.com:

Does anybody have any idea why my postfix server accepted mail for the
non-existent user "<squir...@webmail.cnysupport.com>" (no alias
by that name either)?

I've narrowed it down to a problem with the way subdomains users are
validated.

badu...@cnysupport.com is properly rejected at the rcpt to: command,
while badu...@whatever.cnysupport.com is accepted, then causes an NDR.

Anybody have any ideas?

Yes.  As you were already told, set in main.cf
relay_domains =
ie. set explicitly to an empty value.
