[Exim] Ruoter conditions

Hey all. I need a bit of help on some router conditions. Right now I
have a router with a condition:

condition = "${if eq {$interface_port}{10025} {0}{1}}"

which I interpret as "if the interface port is not 10025", yes?
How could I modify that to be:
"if interface port is not 10025, OR sender address is in this file"?
