Hello to all, we are using the cPanel MailScanner Service Package and it's simply great but we are having some problems with spam bypassing the MailScanner by using some accounts in whitelist.
Unfortunately if you whitelist an address that is an email account on your server, then MailScanner will whitelist to the address if it's sent from or to that account.
sorry to bump up such an old thread but i have the same problem (and my customers too).
we keep receiving tons of SPAM from "ourselves" from a lot of different IP addresses.
There is no email address or domain name in the whitelist in MailScanner, we use both SPF and DKIM in cPanel.
Moreover, Exim has the "Reject SPF failures" option set to ON.
