Hi,
because of a recent spam attack, one of my customers faced, I blocked their own Domain with the "Sender Blacklist" option. In general this works because the smtp-proxy does not block (probably because of the allowed relay settings) mails where the senderaddress is from the customers maildomain. The result is, that only mails from unknown hosts are blocked.
But in this case, the customer gets inbound emails from two other trusted mailsystems, that should be allowed to send mails with the customers domain. Because of this, I wanted to create an exception. But it seems, that this is not possible... I thought I can use a "antispam checking" exception for bypassing the sender blacklist....
Any ideas? What´s about the expression blocking? To what part of the mail is it applied? Can I use this to match the sender address or domain?
