html emails are broken

[oetiker]

Hi

Zimbra 8.8.15_GA_3968 (build 20200921094118)

Since the last update I get a lot of html emails (mainly newsletters) that are not shown right in the zimbra webmailer

Does anybody else the same experience ?

Cheers Manuel

Ours too. We saw that the majority of them were newsletter and similar that have images referred in http:// while zimbra webmail runs on https://
We believed it was a mixed content problem

Confirm this happening on 8.8.15_P14.

This is because new default chrome security settings. Mixing https and http is a security risk and should blocked by the browser.

So there is no way for zimbra to fix this... the emails are just broken... by design...
