pgp signatures

[homega]

Hi,

I most times see pgp signed messages as an attachment in mutt, though others
I see the signatures in the body of the messages.  Why and how's this
difference?  How can one and another been achieved?

Also, could anyone send to me the variables that need to be added for mutt-i
to work with pgp versions 2.6.3i and 5.0i, and with gpg altogether?


TIA

Horacio
