Actually I think the problem is bigger than that.
When a pskaprs email is received from an unknown source (someone not in
the local database) then the server does not know what to put in the
from field. The receiving email server will, most probably, refuse to
handle the email as the from address is not properly formed.
So, we need to check that the user is in the database before the server
acknowledges the message from the pskmail client. Or, we could create a
general user@server address, or we could agree not to handle email from
unknown sources (which in a way is a very good way to solve this).
