I've just completed testing the next generation of my kuvert tool: Version 2.0.0 is out here and has just been uploaded to debian Sid. It's full of Nice New Things that make kuvert more useful, the most notable ones being:

• inbound SMTP support
  You can tell kuvert to listen on localhost on a port of your choice for inbound messages. (This absolutely requires ESMTP authentication as pointed out in the manpage.) Benefit: any garden-variety mail user agent can send via SMTP, which means it can interoperate with kuvert. You don't have to bother with the submission wrapper anymore (but it is still available of course).
• outbound SMTP support
  Kuvert now can speak SMTP to any server of your choice. No more need for a local MTA installation (unless you prefer one, in which case kuvert will work like before).
• support for gpg-agent

There are also quite a few other goodies, but I haven't cooked up a good changes document yet; You'll have to read the manpage.

1.1.13 is available here (and via apt-get install kuvert in debian and ubuntu).

Changes: the pgp-signature part is now tagged a bit more extensively with a content-description and the "canonical" filename; while the filename tag was there in an earlier version (and got removed for reasons lost in time), the content description might help the more...suboptimal mail clients out there.

The prod to do this came from Andreas Labres.

Kuvert is a tool that automatically signs and/or encrypts outgoing email using the PGP/MIME standard (RFC3156), based on the availability of the recipient's key in your keyring.
(more...)

Kuvert was recently featured on the debaday blog, and somebody asked me to put the manual pages on the web.

So here they are, ugly as sin (because I couldn't convince groff or any other converter to render -mdoc manual pages in HTML without breaking them completely):
