As we're discussing e-mails, I know a few folk have said in the past they have sent one to the EDs who then sometimes say they haven't received them.
I sent one the other week, no reply and then yesterday seen in my spam folder, an automatic reply telling me it had been blocked.
"Our system has detected that this message is likely suspicious due to the very low reputation of the sending domain.
To best protect our users from spam, the message has been blocked."
Could that be why some folk have had no response?
