I did not find anything like it, so rolled my own: '%c' format string
to substitute by the email address defined with the new 'contact_email'
keyword. This email is also added to the whitelist.

During my testing I found that Messaging Server post-processed messages
for abuse@, accepting them during SMTP dialog with the sender, and then
milter-greylist refused it during internal dialog between the MTA's
queue handlers which tried to deliver it further to admin@ mailbox.
I haven't seen such behavior with any other target addresses; so YMMV.
Things worked okay when I added this admin@... to rcpt whitelist
as well, so be sure to test your contact address with mails from all
sorts of sources that your deployment should not trust in production.

This worked for me with both a defined email address (any quoted string
actually - something that is not an email address is also happily added
to the rcpt whitelist), and with a missing keyword - at which point %c
substitution in msg texts is empty.

Again, I monkeyed around cloning existing lex code without any deeper
understanding of it, so there may be mistakes... still, this compiled
and worked for me as I expected :)
