I find it easier to start more MX virtuals that run their own postfix + lmtpd to increase throughput and use multiple MX records on domains to distribute the load over the virtuals. If running multiple instances of lmtpd on a single machine is needed, you need either: a preforking setup (which share the address of the listening socket), a threaded lmtpd, or completely separate processes that listen on different addresses or unix-sockets. To use the last solution while sending all mail to the same address (myhost:24) you would need a proxy like haproxy.
