[Evolution] Verifying message

[Alex S Moore <asmoore edge net>]

Using 2.0.2.  I get a pause when displaying a lot of mail which I get
from mailing lists.  Along with getting a line that says 'Valid
signature, cannot verify sender'.  I also get a few 'Invalid signature'.

How can I turn off this check?  I changed my ~/.gnupg/gpg.conf to
disable 'auto-key-retrieve', but that did not make a difference and may
not be what I really want all of the time.

Thanks, Alex
