Perhaps it's a problem with my postfix configuration, but the above
solution bounced the email after smtp, which won't work for us.  I did
find one solution that seems to work...

main.cf:
smtpd_recipient_restrictions ... , check_recipient_access
hash:/etc/postfix/recipient_access

recipient_access:
bogusexample.com 515 Invalid Recipient

...which bounced the email at smtp.  However, when sending a test
message via gmail the bounce error wasn't what I expected:

"[blah, blah, blah.... ] The error that the other server returned was:
515 515 5.7.1 <bogusexample.com>: Recipient address rejected: Invalid
Recipient (state 14)."

The error code appears to be listed 3 times... "515 515 5.7.1"

According to http://www.postfix.org/access.5.html ...' When no code
is specified at the beginning of the text below, Postfix inserts a
default enhanced status code of "5.7.1" '

But, instead, I'm getting my 515 code twice and the 5.7.1 as well. Any ideas?

Thanks,

Curtis
