I'm fairly sure there's not. If you don't like the idea of using iptables, the alternative would be a customised DNS entry for your relayhost. Create a "virtual" relayhost A-record (eg. relayhost.mydomain.com) that returns multiple IP addresses, this will produce a rudimentary form of round-robin. Then just set relayhost=relayhost.mydomain.com in main.cf
