Yes - if the product functions correctly AND if you select "encrypt mail"
in the mail options while composing the new mail note. As far as I can
verify this, the saved mail stored in the "Sent mail" folder is encrypted
when these conditions are met - even if "encrypt saved mail" and "encrypt
sent mail" are NOT checked.

I disagree: when a user composes a mail and specifically requests
encryption for this mail she has good reason to believe that the product
will not pass any clear text of this message over the wire or store plain
text on external systems - regardless of any global settings elsewhere.

In my opinion it is reasonable to expect that if I request encryption by
*any* means within the client, I do not want the clear text to leak out.
And I wish to be told about any problems if my software cannot perform
this action properly for some reason.

In addition I do not think that the "enrypt network traffic" option does
help a lot - the message is still stored on the server in the plain.


Regards,

Martin
