Hello Community,
what is the better practice to blacklist a specific sender i.e. "guy@badguys.com" or "@badguys.com"?
- use "Sender Verification Exception Table" and set the address as "reject", and enable the table on the the table on the mailflowpolicy "blocked"?
or
- use an "Incoming Mail policy" on these senders with an "incoming content filter" that blocks/drop/bounces the mail?
AFAIK the better one should be the exception table, because the mail is already blocked during the SMTP dialog. Is this right?
Regards Roman
