[SOLVED] Image turn into blank gif 1x1 px

Post by brunok » 30 Jan 2020 17:39

Hi!

I encountered a problem with receiving responsive mail marketing.
Some images load and disappear quickly, becoming the blank 1x1 px gif.


Has anyone had this problem?


My MTA is a ZIMBRA, behind EFA.


EDIT1: Found in source message: "WEB BUG FROM".

This is issue!
How to bypass domain from WEB BUG (without allow ALL)?



EDIT2: Created a rule from file that allow some domains and disarm the rest.
