I keep my personal mail on my imap server at home.  Wherever I go, I can then
connect and read it.  Certain remote systems I trust as long as I'm using them,
but they can be rotated without warning.  Though the next user can't login to my
mail server, all of my folders, subject lines and correspondents *are* there. 
It wouldn't surprise me if some messages were cached as well.  I would like the
following options to increase security:

1.  Forget password (effectively logout and stop checking mail on the server)
2.  Either encrypt retained information using the password (which would require
a way to specify it separately in case the password is changed on the server, so
you could still get the data encrypted to a previous password, or else it could
just forget it all and start over), or to purge the retained information on logout.
3.  Similar to the certificate password timeout, set a timelimit for doing the
above automatically.

Reproducible: Always

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a

you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
