Yeah. The OP presumably had his "permit_sasl_authenticated" both in sender
restrictions and relay restrictions. Thats why I gave a example of sender
restrictions where I also said that every instance of
permit_sasl_authenticated need to be replaced (For example, if one is in
recipient restrictions

I also receive a fair amount of spam where the HELO is either my domain
name or my public-facing IP address. I block this as an additional
precaution.
smtpd_helo_restrictions = permit_mynetworks,

You have your permit_sasl_authenticated inside smtpd_sender_restrictions right?
Replace that with "check_sender_access hash:/path/to/file"
Inside the file /path/to/file, you add the following:
mydomain.com permit_sasl_authenticated, reject
Essentially, you move your "permit_sasl_authenticated" to
10 matches
