Support to filter out "Tracking Pixel" in webmail and/or possible regular mail.
The use of "tracking pixel" is a bad for end user security and i suggest to add functionality to webmail but possible also regular mail to filter out tracking pixels.
Especially in EU where GDPR is in effect that users must be informed that a website collects data. Users also have to be able to object to the tracking.
Thanks for sharing your idea. Webmail currently has an option to block HTML images which stops all images from being downloaded, thereby preventing any tracking that would have occurred. When this is enabled, users can choose to download images by clicking a bar in webmail.
To enable the option open MDaemon and go to Setup / Web & IM Services / Settings, check the box for Block HTML images.
Webmail also ignores the SRC attribute on Image tags, and ignores script and link tags in html emails, this functionality all helps to make tracking more difficult, but it is not 100%.

Are you wanting webmail to also be able to identify image tags that are for tracking and filter them out?
If you are, I’m not aware of a good way to do this. We can scan the URLs in the image tags and try to find the ones that are used for tracking, but we don’t really know for sure. And there is no 100% accurate way of determining which URLs are for tracking. The best option is for none of the images to be downloaded.
