filter-dkimsign and multiple domains

I saw the recent thread regarding multiple domains and filter-dkimsign.

I just wanted to add in my $.02 that I prefer to have as much
proof-of-work as reasonable since it seems, at least a little, to help
with inboxing at the oligopoly providers. The trend for them to direct
legitimate mail to spam filters has been notching up year-by-year, and
having the domain of the DKIM signature match the from address seems
like an easy check for them to perform.

My purpose for filter-dkimsign is on a webserver that sends
transactional email for several domains.

A solution that would work for me does not have to be complex or
feature-rich. For example, if there were an option to sign with whatever
domain is in the from address (everything after '@'), that would be perfect.

In any case, thank you for the very easy to implement DKIM signing solution.
