can you deny you sent a signed e-mail?

Really?  How does this differ from a regular (handwritten) signature?

Handwriting experts can be fooled, so even in the situation where you
get an "expert" opinion (i.e. court) a signature is only as
trustworthy as the participants define it.

At least with a digital signature you can revoke it and (providing
your correspondents update your key regularly) the potential for
fraudulently signatures is time limited.

I'd love to be corrected by someone who knows more about this than me
though...


Cheers,

S.
