[Exim] question

Is smtp_accept_max_per_host is the only variable which can be set by
lookup/lsearch like this:

${lookup{${mask:$sender_host_address/24}}lsearch*{/usr/exim/smtp_accept_max_per_host.cfg}}

?

I've tried to set

recipients_max
smtp_accept_max_per_connection

but failed. I would like to set them too. Any suggestions?
