Er, wait, not quite; I was tired last night originally had a lookup
there, which I switched to match_ip and didn't notice that I'd left
$value in place. I'm sorry.

I should have written:

message_size_limit = ${lookup {$sender_host_address}iplsearch{/some/file}{$value}{50M}}

In your case, there's no value associated with the value in a hostlist;
it just is present or is not. So you want something like:

message_size_limit = ${if match_ip{$sender_host_address}{+printer_ips}{200M}{50M}}

Sorry for the misinformation.
