All of the software is, of course, open-source/free software but the iRedMail-Pro "management" application is what you are paying for (there is also a free version w/ less features). You can certainly implement everything yourself from scratch without paying for it.
I'm not a customer and have not used it although I did look into it a while back. The few people I asked who had used it were satisfied with what they received for the price. YMMV.
Interesting. I'm author of iRedMail project (Zhang Huangbin), and i'm a HN fan. :)

I saw this post, then registered an account to say something (I forgot my old account coz I read HN with RSS, not web).
