[exim] Limit Inbound E-mail to Certain IP Range Per cPanel D…

Hello,

I'm trawling through the Exim ACL documentation but don't think I can
find a way to for this to work.

I'm trying to make it so only a certain IP range will be allowed through
Exim to a specific domain, with other domains unaffected by this ACL.

Is something like this possible? If so, where might I start looking? For
more context, this is in cPanel, though I imagine that just adds an
unnecessary layer of complexity to the question.

Thank you,
