Re: StR
Not necessary. It's a per-message flag, and I'm sure that AquaMail does sync it from the server if set.
The \Replied flag is mandatory in IMAP, the $Forwarded flag is optional.
If the server doesn't support $Forwarded (it happens), AquaMail uses the \Replied flag (when it's the one wanting to set this flag).
The best way to diagnose this is to long press the account in AquaMail -> Diag: message dates -> select the appropriate folder -> run the test -> at the end, the app will prompt to send me a log file.
The log has message IDs, dates, and flags. Then I'll be able to see what's there in server responses.
