[SOLVED] Image turn into blank gif 1x1 px

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.
