1. For easier management and configuration the ability
to use regular expression for the '-d switch' would be
very useful. I can't get away from the DNS piece, but
having fewer changes to track and manage on the mail
side is important. Currently to add a domain to be
signed one needs to add the domain to the filter and
restart the process. This is not only time consuming
but difficult to manage in a large environment. To
ease filter management implementation of regular
expression would be beneficial.
2. If I could sign _ALL_ emails and not just the ones
that match a certain domain would also be helpful.
This could be managed through the request above or
separate (-d *). If I only could choose one of the two
then this second request is more important.
Perhaps something like:
In addition to the above requirements the use of the
'-b s' flag to ensure the purpose for send-only could
also be added.
PS -- Add this to dkim and dk please.
