More control of DKIM

We could really do with more control of DKIM, for example...

Ability to control key length 1024Bit or 2048Bit (server wide)
Enable subdomain signing, while you can't create email accounts for subdomains in Plesk, it's often the case that the server is named as a subdomain eg: mail.example.com Which means unsigned mail leaving the server (cron etc) even when example.com is hosted.
The standard OpenDKIM package allows you to add it to nonsmtpdmilters so sendmail mail gets signed.
Ability to change the selector.

We really can't have mail leaving servers not being signed...it defeats the whole point in having it!

Please vote!

Thanks!

My business customers can not contact public authorities or government, because the mails gets rejected. DKIM 1024Bit is marked as deprecated.

2048Bit DKIM key support MUST be added ASAP!! Gmail now requires 2048Bit for sending emails to Gmail recipients per: https://support.google.com/a/answer/174124

Yes - should be possible as soon as possible.
Only signing the headers To, From and Subject is not enough to current security conditions.
