From the "About Lamson" page:
However, as great as Lamson is for processing email intelligently, it isnt the best solution for delivering mail. There is 30+ years of SMTP lore and myth stored in the code of mail servers such as Postfix and Exim that would take years to replicate and make efficient. Being a practical project, Lamson defers to much more capable SMTP servers for the grunt work of getting the mail to the final recipient.
