Not sure if I should be chasing this down with my Web/Email host (I use their SMTP server to send messages) or if it’s my own issue.
mail.Headers.AddHeader("X-MyHeaderHere", "MyHeaderValueHere")
When I inspect the message as it’s being sent, it has the header as it’s send thru SMTPSecureSocket, but when the email is received the header isn’t there.
