Questions about Cdosys:
-
you are trying to relay mail thru a server that isn't setup for that. most email servers are setup to not allow email to be sent thru it unless it originates on that server (or from a list of trusted IPs or domains). this cuts down on spam. you will need to contact somebody how is in charge of the email server and have them work with you to allow your app to send email thru the email server.
I think you mean, you want to change the timestamp of a message sent via CDOSYS to be earlier than the actual time.
The short answer is, in the IMessage interface, the SentOn property is read-only and based on the server's clock, so if you want to forge it, you need to set the server's clock back.
The same holds true in .NET with the Message class.
