I am debugging a problem with my Azure VM Windows server receiving SMTP from the Internet, and want to use Wireshark to show ONLY SMTP.
I would also like to use Wireshark to show the contents of the SMTP message to see if it is what I sent.
I cannot figure out, nor find help, on just simply making Wireshark show only SMTP. Wireshark doc says to set filter to SMTP, but that does not work for me.
