PointOfMail Email Tracker (Client) Detection

Medium Nessus Network Monitor Plugin ID 3411


The remote host passes information across the network in an insecure manner.


The remote host has opened an email that is being tracked by PointofMail. This software embeds a tiny HTML link within an email such that when the user opens or highlights the email, a connection is made to an Internet server that tells the email sender when the email was opened, the operating system of the recipient, the email client of the recipient, the geographic location of the recipient, and more.


Use anti-spam software to block 'phone home' applications or disable HTML within the email reader.
