My manager at the time turned white as a sheet when he found out I did that.

I second Mailcow. I use it on a residential IP and have a smarthost for relaying in/out since my isp blocks port 25.
For relay, I use mxroute.com, I have a lifetime account and Mailcow has a fetchmail option.
If you are concerned about TruNAS, go look at Xigmanas. This is the original FreeNAS project before iX acquired the name.
