We're running a Zimbra server, Release 8.8.15.GA.3829.UBUNTU16.64 UBUNTU16_64 FOSS edition, Patch 8.8.15_P2 on Ubuntu 16.04.6 LTS.
I have a strange problem with an email that a user sent. It was created with various fonts and colors, generating an HTML format email. The person sent the email, however, the recipients who are also using Zimbra, as well as the archived copy in the user's Sent items displays the message as missing a large portion of the text content. If I use the "Show Original", all the text is there, but through Zimbra's web client, the text is missing. I've saved the original as an EML file and opened it in my native mail program and all of the email's contents is there and displays. Unfortunately, it is an internal email and I cannot share it's exact contents.
I realize the difficulty in troubleshooting something without seeing it, but has anyone seen this type of behavior and possible have some kind of fix or workaround?
Any help greatly appreciated!!
Update: Temporarily solved with a workaround:
Code: Select all
zmlocalconfig -e zimbra_use_owasp_html_sanitizer = false
