[Dovecot] E-Mail Encryption

[Christian Felsing]

So I have to inspect zlib plugin (and Dovecot) code ;-) If plugin
"knows" username, it needs a way to get user password in clear text and
of course his username to find and decrypt users private key. These
items have to be saved in a secure way, while user is logged in.
Obviously there are several differences to zlib plugin. If plugin API
supports these extra requirements, it should be possible to write such a
plugin which will stay compatible to future Dovecot versions.

Encryption should be done in deliver tool, so there is no requirement to
touch MTA (e.g. Postfix) code. Deliver tool must know dest. mail adress,
so it can ask LDAP for the right public key. Does deliver also support
plugins ?
