Hi,
I have "CheckMailerDomain" "1" in server.tab.
I have not received some important emails from Yahoo because of this. The
sender address does not have a valid A record, but it does have a MX-record.
In my opinion, it should not be blocking these messages. I'm running v1.22.
The docs states:
[CheckMailerDomain]
Enable validation of the sender domain ('MAIL FROM:<[EMAIL PROTECTED]>') by
looking up
DNS/MX entries.
And yes, my DNS servers are up and running just fine.
What is the rule for CheckMailerDomain to cause this to be blocked?
Thanks.
-Don
