filter mail to another folder always shows as read
I have a filter set up to reroute incoming email from my inbox to another folder based on the from address or the subject contains a certain string. This works fine. However the email in the target folder is always marked as read, even though it hasn't been read.
The Filter: Getting new mail is checked (filter before Junk) Match any of the following From contains [a string] Subject contains a [a string] From contains [a string] Perform these actions: Move message to [target folder] Mark as unread Forward message to [another email address]
Recap - filter works redirecting the email to the target folder and forwarding a copy. email in target folder is always marked read. This happens with "Mark as unread" in the filter and without it in the filter.
Filter log shows message moved to target folder, email forwarded to [another email address], and message marked as unread.
This IMAP email on a Zimbra server. Thunderbird is v68.1.0 (32 bit). OS is Win 10 Pro x64 Build 17134

I noticed something more - I have another IMAP account with a similar setup - a filter to route incoming email into another folder. This one doesn't forward to another mail address like the one above does though. Emails it forwards do appear in the forwarded to folder as unread.
Setup doesn't appear to be different in any way that would explain why one works properly but the other doesn't.
