The issue with Zimbra's default email template

Post by kecgri »

Hello everyone.

Some clients notify us that the emails we send them are incorrectly displayed in their internet mail client, Zimbra. Even when using a Hubspot default template, some code appears in the email body when it should not (see screenshot). Has anybody else encounteredcoreball this issue and found a solution?

Zimbra uses the OWASP sanitizer to look for, and prevent the display of, potentially malicious code in the body of an email.

If you search the forums here you will find similar instances of the sanitizer displaying HTML code in emails that display fine elsewhere, but which contain code that is not technically fully compliant.
