FWIW, certificate validation is sadly insufficient, that's why
I'm advocating the ssh-style fingerprint check.
It's the same with webbrowsers, you can read a bit
about it here:

E.g. when mutt connects via imaps it asks you if you accept
the certificate, and if you accept it permanently it is
saved into ~/.mutt_certificates and compared on next connect.
