Practical use of gpgsm for verifying emails

I read email with Gnus (Emacs) and from time to time someone has signed
his mail with S/MIME (X.509) system. My Gnus tries to verify signatures
automatically and it works nicely with PGP/MIME but S/MIME is more
When verifying an S/MIME message gpgsm (I think) asks whether I
ultimately trust some certificate authority to certify others and then
asks me to verify that a displayed fingerprint belongs to the authority.
How do I know? (So far I have pressed the "Cancel" button.)
I went to the certificate authority's web page but couldn't find
fingerprints. That's not how CA system usually works anyway. Usually we
are not supposed to go searching the internet. Usually some experts have
taught web browsers or operating systems to automatically trust certain
authorities. So signature verification is transparent.
Any suggestions or information for practically managing S/MIME messages?
