Let's just take the first.
23:57:05 35137 /considering: ${if forany{test.host.net :
SECONDHOSTNAMEPERHAPSWILDCARD }{bool_lax{${if forany{ A@${item} :
B@${item} }{bool_lax{${if forany{ C,${item} : D,${item}
}{bool_lax{${lookup{${item}}lsearch{/usr/local/etc/sender-recipient-override.txt-manual}{LOOKUPORDEFAULTRESULT}}}}{$value}}}}}}}}
After macro expansion, the router is dealing with that. Given the
CAPITAL LETTERS in it, I suspect you have macro problems which need
sorting out before you get to worrying over lookups.
Start with the rules on macros.
