Subject: Re: Save a copy of emails sent with .NET SMTP client

Saving a copy is a mail client feature that's usually implemented using IMAP - it's not an SMTP feature at all.
So it makes sense it's not in the SMTP client library.

And you will probably not be able to do that using CGP rules, unfortunately, as I don't think you can base such an action on the Reply-To header content.

If I was assigned to do this, I would probably use an IMAP library, connect with an user/password that have MASTER rights or rights to write into user mailboxes, then save a copy of the message there. But that also means creating the message structure itself as, if I don't remember the NET SMTP class or the MailMessage class having a method to get the generated message structure.

A server rule could however be used to save all the outgoing messages in a single mailbox.

Or an external filter could be written ti intercept the message, analyze its content, get the Reply-To header and use IMAP to store a copy in the correct location.

Sorry, I don't think there's a straightforward and easy solution for this problem.

So Im trying to work out how to do this with CGP rules.
We have a web app (.NET) which generates email orders and sends to 3rd parties, works well. But would like to save a copy in the users sent folder.
Order emails are sent through account (From address) and the Reply to address is set to 
So would like to have a rule, if from: then Store in Messages
(where userx is a variable IE Reply to address)
Is this possible to do this with a server based rule
Any suggestion welcome
