Detailed Description

-- generate signature and attach in DKIM header to outgoing message

Steps:

a) DKIM controls: get private key for sending domain b) Prepare two staging files at queue/dkim (before and after signing) c) Read input at fd0 and insert CR for every line and store at dkim/x/pre d) DKIM sign the message with provided private key and store at dkim/y/post e) Copy signed file from fd to 0 f) Invoke qmail-remote (respecting the \r
) g) Remove staging files (pre/post)

Hack for hybrid signatures:

a) selector is a link to RSA private key b) selector2 is a link to Ed25519 private key c) Both are provided in the 'selector' field of dkimdomains separated by colon d) The coupled selector information is provided to qmail-dkim as: -yselector ,-Yselector2 e) The RSA privat key is given unaltered f) The Ed25519 private is supplied as additional argument
