Meta UI: Am I out of my mind?

I'm considering volunteering[1] to set up a mail server for a friend.
I'm not concerned about the technical details, and this froup would be
the wrong venue to ask if I were, so please don't tell me that S
sucks, E is egregious or P is putrescent. However, I'm interested in
your thoughts about the non-technical aspects, and any sad sagas from
those who have done something similar[2][3].

The issues that I'm concerned about include making clear what I will
and won't do and sticking to limits once I've imposed them. He's a
programmer, but basically knows nothing about SMTP or TCP/IP. I'm not
sure whether to try training him to maintain things himself, or
whether it would be less work to have him treat it as a black box once
I set it up. And, no, my people skills are not as good as I might

Am I out of my mind for considering it?

[1] The Cadre must think that I'm dense, never having learned that
critical Army mantra, "Never volunteer!"

[2] That is, setting up a server in a context that is not job

[3] I understand that you might have to mention some technical
details as background, but what I'm looking for is people
