Hello friends!
In Web mail we've found some bug. If user has some message with Outlook conditional CSS in message's content in his mailbox, exactly with condition like this:
<!--[if !mso]><!--> https://domain.tld <!--<![endif]-->
and we will try open this message SOGo filters out this content of the message from displayed content. But when we look in View message source, we can see that this content in this message's source.
Can somebody explain, please. Is this a bug or some protection for security reason.
In other clients, for example in Thunderbird conten like this displays normal.
