Messaging Gateway

Hi,

In our smtp gateway, our own domain is added to the list of Blocked Senders. Here, it is clear that inbound emails claiming to come from our domain will be rejected. My question is about the alert notifications. When notifications sender mail address is from our own domain, similary I expect to see that alert notifications will be blocked by the gateway because our domain is in the Blocked Senders. But, the situation is a little bit obscure. I have two smtp addresses connected with the same domain user account. (both smtp addresses present in proxy address attribute of the user) When I have two administrators with these email addresses, only one of the administrators gets notications. That administrator has the email address which is present in the mail attribute of the related domain user. When the message audit logs are investigated, recipient data for both notification mails are as follows:

(notification not blocked)

Verdict => Reinsert

(notification blocked)

Verdict => System denied email address or domain

Simply, my question is that why there are two cases like this while sending alert notifications.

　

The reason notifications are not blocked is becuase we don't scan them as if they came from the internet. They originate with us and go straight out to the mail host. We don't put anythign special into the message that stops us from blocking them, otherwise we would be giving spam senders a way to bypass us.

If for any reason the message has to be scanned becuase the message needed to go out to the internet or to some other host, its possble we did scan them and they would get blocked. In thise case you should add the sender email address to the known good sender's domains which will override the bad sender's domain.
