RETURN EMAIL DNS CHECK SUGGESTION
I'm not sure if Fortinet people read this, but if they do, I have a suggestion:
For email, there is an option to check the return address of email to see if its
valid. "Return Email DNS Check"
Seems like a good idea, except, it seems pretty common practice for companies to
tweak the return address so that YOU CAN'T REPLY to it. What they do is add a
"fake subdomain," before the domain name. For example, progressive insurance
might send out an email with a return address
of: customerservice@e.progressive.com That email address is not valid, but if
you remove the e part then customerservice@progressive.com is valid. Here are
some others:
donotreply@info.aps.com
emailclub@marketing.jerseymikes.com
So my suggestion. When doing the return address DNS check, ONLY use the full
domain name for the DNS check, and remove the subdomain name. I wish I could
tell it to do that, but there isn't a way I can see.
