that. Spamdyke false positives are practically nonexistent though, so you

Even if Spamdyke is correct, it does not mean that the end behaviour
is what the customer expects.
I have ran into issues where customers haven't received email they
were expecting because of Spamdyke rejecting a message because of
missing reserve dns. And it does not help telling the customer that
the sending server is not properly configured, if they can receive the
same email with their Gmail or some other account...
Gmail would reject that as well, ttbomk. Many mailers these days are
rejecting based on missing rDNS. These cases seem to be less frequent as
admins get their server configurations fixed.
Good point though. I usually try to contact the the sender's admin and
have them fix it. They're typically glad to do so, as it helps their
deliverability in general. In the meantime, it's easy enough to whitelist.
I have been playing around with an idea that I should create a page
for each customer where they could check the sending addresses for
denied messages. So if there is a "real" message denied I could then
offer an option to white list that mail server or sending address, so
that the customer could try contacting the sender again.
Giving the customer more visibility/control is usually a good thing in
my mind. At this point, the sender typically contacts the receiver by
another method (phone, postal mail) to let them know about the
rejection, which seems adequate to me. The line has to be drawn
somewhere though, and the policy I favor is that if the sender's server
isn't configured properly, they need to fix it. I do whitelist
occasionally though as an interim measure.
