virtual mailboxes

[Claus Atzenbeck]

Hi all:

I read that Alpine supports virtual mailboxes, however, I could not find
out how I possibly can create or manage them. Does someone has a pointer
to that?

Can a virtual mailbox span over multiple other mailboxes, e.g. show all
messages of all mailboxes inside a specific folder that are flagged
important?

Thanks.
