[Dovecot] Does a plugin can have root privileges ?

Hello,

I wish to get "Fetchmail Wake" works in my environment. This plugin send SIGUSR1 to fetchmail so it wakes up when mail client grabs mail.

For the moment "Fetchmail Wake" is executed by mail_uid (defined in dovecot.conf) which is not enough to send signal to fetchmail daemon (and access to fetchmail.pidfile).

Thank you!
