Summary: draft-ietf-dkim-ssp-10 / RFC-5617 made Author Domain
Signature based on 'd'
AssignedTo: dev@spam... ReportedBy: Mark.Martinec@ijs....
Rats, I just noticed that in May 2009 a change from draft-ietf-dkim-ssp-09
to -10 (and subsequently published as RFC 5617 in August 2009) changed
the definition of author signature (which was based on 'i' signature tag)
and renamed it to 'author domain signature', and made it based on a 'd' tag.
The DKIM plugin still implements the former definition.
I'll prepare a change to comply with RFC 5617 (ADSP).
In practice there shouldn't be much difference (e.g. in whitelisting),
as the 'i' tag (identity) is rarely a subdomain of a 'd' (signing domain)
- typically the domain in identity is exactly the same as the domain in
a 'd' tag (explicitly or by default).
