Fixed by adding brackets - etc...
dkim_domain = ${lookup mysql {select domain from admin WHERE
domain='${quote_mysql:${domain:$h_from:}}' limit 1}}
Whether this is correct or not - it works. I needed the domain of the
sender so I can provide the correct DKIM data. This was somewhat easier
before Tainted Data controls though in this case - all I'm looking for
is finding the correct DKIM records which only exist for Domains that I
manage... so is somewhat self-controlled already.
