a way to say if it received from authorized MX
Posted: 08 Aug 2016 08:05
Suppose i receive an email from user@sample.com
If sample.com have a SPF or DKIM I can be sure that email come from sample.com
But if it have no DKIM and no SPF i think there is another way to get some Others
set type=mx
mail.sample.com 212.33.56.77
mail2.sample.com 113.64.61.14
I need a rule that be matched if a mail of sample.com come from 212.33.56.77 or 113.64.61.14
Is it possible ?
Better will be classC sender.com from 212.33.56 or 113.64.61 so if they use an outgoing server on the same class it is also matched
Thx
