Probably not... while LMTP is based on SMTP, it forbids a couple of concepts, such as queues and authentication. I do think it would be possible to write an SMTP daemon that would just "play dumb" if it received an LHLO instead of HELO or EHLO (ie. the client said "let's speak in LMTP today") but using an SMTP framework for an LMTP server is probably overkill.
