@st3iny i can reproduce this too. I have a message that the certificate is verified, but still shows a warning.

Can confirm this with Mail app version 3.6.0 as well. A bit unfortunate because it means signing your mail with PGP will result a warning that results in less trust than a mail that isn't signed at all.
