I'm an opensmtpd developer.

As far as opensmtpd is concerned, it is production ready and has been used in high volume environments sending mails to millions of recipients daily, handling multi-million queues.

The project was started in 2008 so when it comes to being run in production environments, I think we can claim that it's ready :-)

Now as for the what you would gain, I won't do proselytism, we have published a couple presentations on our website which describe how it works and some of the technical details behind it. You will also find lots of technical details on my blog where I post mostly about OpenSMTPD internals.

If you have a running Postfix, I suggest you don't shift but keep your working setup. If you intend to setup a new MX, you should definitely give a try and see how it goes for you.

Thank you very much! I shall have a look. I'm thinking of moving servers and setting everything up from scratch in order to modernize all my services and remove legacy cruft. I will definitely consider opensmtpd.
