Good afternoon (I assume).
I’ve been asked to solve a problem that is occurring when trying to send an email through an Exchange 2016 server.
The issue is that the dialog results in an exception:
“<span style=“background-color: rgb(255, 255, 255); font-family: “Segoe UI”, Tahoma, Arial, Verdana; font-size: 12px;”>The server committed a protocol violation. The server response was: Enter mail, end with “.” on a line by itself’.”
(of which I was never aware that it was a protocol violation for an SMTP listener to say, hehheh).
Anyway: if I come up with a little prototype program that uses Aspose.Email to do this, my prototype runs against any SMTP host I can find - but at the customer site, it coughs up this error.
Is there a way to (just like possible with System.Net.Mail, see
http://www.systemnetmail.com/faq/4.10.aspx for more info) to get a dump of the actual smtp dialog, or other information that would be useful for figuring out what might cause this to happen?
