Unable to make a copy of send mail in yahoo 'Sent' Folder while sending the email through smtp email client.
I have a requirement to track the 'send email's' using their email GUID's with a .Net application.
Step1: I use smtp email client (.NET based) for sending emails. I add an additional header (contains GUID) to identify the email (Note: smtp doesn't give the GUID of the send email|). Step2: I search the email with the particular header in the Sent Folder
I can execute Step1 successfully. I can't execute step2 beacause email client doesn't make copy of send mail in yahoo sent folder.
Is there any option to force the email client OR yahoo smtp to make a copy in sent folder?
