Rather than a) hard-coding a list and b) ignoring a negated list, might
I suggest something more like:
domainlist avoid_oath_mxes = *.yahoodns.net
dns_yahoo_aol:
debug_print = "R: dnslookup_yahoo_aol for $local_part@$domain"
driver = dnslookup
condition = ${if forany{${lookup dnsdb{>: mxh=$domain}}}{match_domain{$item}{+avoid_oath_mxes}}}
transport = remote_smtp_smarthost
route_list = * mx.localrelay.com byname
