The Postfix project aims for code quality, security and backwards
compatibility over hastily deployed shiny new features.  You'll

The main "limitation" to keep in mind is that the Postfix concurrency
model is multi-process no multi-thread.  So issues related to thread-safety
don't arise and are not addressed.
