[PATCH 3/4] xen/manage: Guard against user-space initiated poweroff and XenBus.
There is a race case where the user does ''poweroff''

Ways to poke and prod Dovecot?
I'm a newbie and want to learn more about Dovecot. I can install it in a
test bed but am not sure how to run it so it shows me what it's doing but
i'm not actually mailing stuff. Is there a doc somewhere?
Thanks!
