Send email without leaving a copy in the Sent folder

Question

I am using the SmtpClient to send to new users the credentials when the Admin creates them in the System. And everytime the user itself (not the Admin) updates his Account i send an email about the new credentials in case the user changes the Username or the Password.

So what i want is not to save a copy of the sent emails in the Sent folder.

I am working with C# and developing a WPF application.

So is it possible to send an email without leaving a copy?

I am just trying to avoid leaving a copy in the Sent folder because the credentials of the all the users will be there in the Sent emails.

Thansk in advance!

Found on Gmail forum

There is no option to not save sent messages in Gmail, but you can create a filter to delete all sent mail. Create a filter with "me" in the From field, and set it to delete. The messages will be put in the Trash immediately.
