Depends on how you set it up. SpamAssassin checks all the received headers. DNSBL blocking (at XMail level, not at SpamAssassin level) checks only the IP address that is connecting to you. So it *shouldn't* produce false positives - unless the IP address connecting to you meets both the "dynamic address" and "legitimate mail server" criteria. And for those, they can be whitelisted locally as needed.... - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
