Maildir P flag?

Hi,

I use Thunderbird with a mailredirect addon. It used to show me which emails were redirected. I believe it used the "P" Maildiir flag for this status.

Now it seems that none of my email store has any file with a flag of P.

Is this something that dovecot may have adjusted with my mail store?

And if so, why?

If not, any ideas where I might look for the next "culprit"? ;-)

Thanks AndrewM
