I'd split these functions to a separate device, using pfSense on
embedded hardware (ALIX or comparable).
They have no point on a server. pfSense does this on 200 $-size hardware
with 5 Watt energy consumption.

I don't think there's a free version for everything ;-)
Zimbra is OK, but the commercial edition costs - same with OX and most
other stuff.
Given the complexity of the stuff involved, I'd say anything like this
needs a commercial backer.
Unless you only use mail.

For free?
;-)

I have a sense of deja-vu. Didn't we have all these questions and specs
a couple of weeks ago?
