Hi Mats,

In an Acme window, try running:

Local upas/fs -f /imaps/your.mailserver.dom/username

On a Raspberry Pi, this may take a few seconds to complete with a
large mailbox.  You will know it is finished because the `fs' process
will disappear from the upper left-hand corner of Acme's tag line.
Then (also in an Acme window) run:

Mail

It helps if you already have auth/fgui running to receive your
password (if it isn't already loaded into factotum).

Best regards,
Peter
