DSN != reply
Replies have a return path.
DSNs have an empty return path - making them trivially distinguishable.
Apparently those clueless virus/spam filter writers are not alone.
It doesn't matter who the sender is. If the postmaster at some site
opens his mailbox one morning and discovers a flood of warnings from
your software, guess what his response is likely to be.
If he is that clueless, then his mailbox is *already* full of
spam claiming to be from me. My domain is popular with spammers for
some reason. I've gotten death threats from such clueless postmasters. If
this clueless postmaster does not do basic forgery checks, then the 1 DSN from
my software won't even be noticed.
I'll repeat this in more detail, since you don't seem to be aware of
the basic features and purpose of DSNs.
I'm aware of what DSN's are for, stop trying to be condescending.
Are you ever going to send more than one warning to any given domain?
