I have a guess though, or alternatively a suggestion if it already doesn't work like that:

lmtp:tcp:lmtp.example.com:24

where lmtp.example.com expands to your two IP addresses. DNS server handles load balancing by returning IPs in round robin and Postfix handles fallbacking to the second IP if the first one doesn't work. Dovecot has similar behavior in several places.
