Emails sent from SF (composed by Nintex DocGen, the 3rd party doc merge platform we use) that contain linked images are having the image URL truncated, I think by SF, so the email arrives displaying "servlet/servlet.ImageServer?id=......" instead of "https://myorg.file.force.com/servlet/servlet.ImageServer?id=...." (which would cause the image to be rendered).
This used to work, so something changed recently.
My images are stored as Classic Documents with Externally Available Image checked.
I suspect this is some sort of SF Email setting issue but I can't figure it out.
Any thoughts?
@Kermit Del Rosario The images are .png files. I obtained the URLs by right-clicking on the actual images in Documents and choosing Copy Image Link. I can paste the URL into another browser not logged into SF and it renders successfully with the full URL that starts with a full domain name. It's only the received email that has the URL truncated (and I tried two different email providers).
