Email - iRedMail in perticular

I'm looking to set up a lightweight email server using Alpine as a base, but as a linux-noob (only been unix-ing for a year) I am having some issues.

The walkthroughs in the wiki seem to be outdated, so I have gotten caught up a few times.

I have had success with iRedMail on other platforms, but would like to stay away from systemd as much as I can. Has anyone been able to get this working in Alpine? I found some old (2010-2012) posts on iRedMail's site asking for a working package, but it seem to have not happened.

So if anyone has got it working please let me know how you did it, or if you can point me to a more up-to-date how-to for setting up email on Alpine it would be greatly appreciated!!
