So it doesn't perform any form of domain-only mapping at RCPT TO time?
What about a regexp form like:
/^(.*)@example\.com$/ $...@example.net <mailto:1...@example.net>
That also defeats recipient validation.
As an alternative, you may be able to use smtp_generic_maps to
rewrite the destination domain on the fly during delivery. See:
http://www.postfix.org/ADDRESS_REWRITING_README.html#generic
I do want the username checked during SMTP arrival time. Will it do so
for the virtual_alias_maps if I use regexp: format?
If smtp_generic_maps suit your needs, they will not affect
recipient validation, and may be easier to implement.
