I’ve an issue with an spammer and I’m trying to block the domain name @ib.standardbank.co.za on the global blacklist (one per line) on the Spam Assassin configuraion trough iworx.
But copying this line: @ib.standardbank.co.za gives me a warning message that’s not a proper value… how can I block an entire domain here?
I have a question about it. If I wanted to do the same (to block an email address), what is the difference between to set in this way (SpamAssassin global blacklist) or add the email address in the MTA Settings -> MTA Level Inbound E-mail Address Blacklist?
The difference I believe is at MTA level the email is not received but rejected, whilst at spamassasin, the email is received then filtered to spam account or deleted, or subject to any conditions you may have set.
