Seeing outgoing e-mails sent from web clients, with WFP RRS feed

  • Question

  • Hi everyone,

    Is this even possible to know that an email is sent, if the user send it through a web client (with an App_ID maybe ?)

    I know that emails sent through web clients are transmitted as https packet before it reach the web mail server, so it seems that I will not be able to figure out an email have been sent by looking into the packets. I looked into a lot of functions and layers to look into, I am about to give up, so I give a last chance here : Is there a way that I could know an email have been sent from a computer if the user made it through a web client such as gmail or outlook ? Also, if it is possible, can I know the size of the email ?

    Thank you !
