I was wondering ... as #email encryption via PGP/GnuPG is not suitable for true and ongoing end-to-end confidentiality. But what about authenticity of mails? I dislike S/MIME for its corporate nature, and #PGP via PGP/MIME is well enough supported by many (free) mail clients.

What's the #cryptography or #security community's view on PGP for signing emails? Or what would a suitable alternative be? I haven't come across any, though.
