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.
