That's got nothing to do with "techies" (apart from the paradox effect that non-techies, supposedly better in communicating, which I don't believe, BTW, cannot help you with techie topics --- LOL).
It will also not be for you as soon as you have had the first client insisting that their not understanding is all your problem despite their unwillingness to do their homework.
I have come to the conclusion that one can only do helpline with a guaranteed response (aka service level) for money (either a lot or because you are desperate and really need it).
For free, as community engagement, it's only possible to help people when the vibes are right: We feel with them or like their approach. Or learn a bit about teaching.
That said (and if you still got your problems 4 months later), you can always ask your mastodon timeline, subscribe to tags like #email, #postfix and build yourself a list of people which are savvy on these topics and might be willing to answer the odd question (if asked nicely / in the right way).
Maybe there are even mailing lists or still the one or the other usenet group. Stackoverflow might also still work for these topics (likely most nearest to the personal helpdesk you desire).
