IBM Enterprise Content Management - Chrome 88 Issues downloading .eml files with mime type message/rfc822

[Mark Jordan]

Hi Team-

I work with the IBM team that manages support and dev for multiple java based web applications that include functionality to download content via HTTP/HTTPS.  You can review our business footprint here:

IBM Cloud | IBM

Our issue:

At the Chrome 88 level we saw cases come in where clients are unable to download .eml files that have the mime type of message/rfc822.  We see these failure via both HTTP and HTTPS in Chrome 88.

It succeeds in all lower Chrome builds.  We thought is was related to the mixed content download security changes in Chrome 88 but the fact it occurs via HTTPS removed it from that line of troubleshooting.

We cannot account for the security block for the specific mixed content type within the application code / config level.  We cannot find a way to revert the block in Chrome 88 controls.

Is this a known issue?

I can offer HAR files showing it fail in Chrome 88 and succeed in Chrome 87 if needed.  Or any other diagnostics required, of course, including a sample .eml file.  You should be able to easily replicate this by storing an .eml file at a location where it can be downloaded via the browser.

Please advise as this is something we need to manage with a very large enterprise client base.

Thanks,

Hi Greg -

All sorted!  I found the chromium bug reporting process after I sent this.  Thanks for the reply, though.
