Advisory: Sophos Email Appliance Time of Click (ToC) feature is breaking embedded images in emails.
Embedded images refer to a URL in the email where the image is hosted. It is this URL that ToC is re-writing. When the mail client tries to load the image it receive the block web page, which the mail client does not know how to render. Instead it will display a message that it failed to load.
Applies to the following Sophos product(s) and version(s) Sophos Email Appliance 184.108.40.206
Email with embedded image will fail to load making the email hard to read for users.
This issue has been resolved with the release of SEA v220.127.116.11
