Hi, Stephen! Thanks for the DNS tips---you're the first person to
respond.
Also, keep us in the loop about what you figure out about DKIM!
With DNS figured out, I think the main obstacle to setting up DKIM is
getting the mail transfer agent (Exim, I think) to sign outgoing
messages. I think an admin would have to do this, since I can't see any
way to configure Exim from within my file space. I've opened a Bugzilla
request asking the admins if they can set up message signing (or if I
can actually do it myself), but no one's responded to it yet:
https://bugzilla.hcoop.net/show_bug.cgi?id=1376
If any of you know a way to access Exim settings as a normal user, I'd
love to hear about it.
Best,
Aaron
Hi Aaron. Maybe you already got help off list, but if not:

Here's a snippet of what I use for SPF, you can look up my website to
see how it turns out:
dom "smichel.me" where
CreateWWW = false;
with
dnsDefaultText "v=spf1 mx ~all";
end

Yes, dnsAlias is a CNAME to whatever the main domain is. Here's the
full entry that I use for pointing jabber.smichel.me at a hosted
snikket server.
domain "jabber.smichel.me"
with
nameserver "ns1.hcoop.net";
nameserver "ns2.hcoop.net";
(* values for snikket servers *)
dnsDefault "49.13.15.16"; (* A record *)
dnsDefaultv6 "2a01:4f8:c012:4a65::1"; (* AAAA record *)
dnsAlias "groups" "jabber.smichel.me"; (* CNAME
groups.jabber.smichel.me jabber.smichel.me *)
dnsAlias "share" "jabber.smichel.me"; (* CNAME
share.jabber.smichel.me jabber.smichel.me *)
end;
I couldn't figoure out how to cname something more than one subdomain
deep (aka include the config above inside my config for smichel.me). I
imagine you'd just need to make another `domain` entry like I did here.

There's two other ways I use.
The easiest thing is to look through other people's domtool configs;
they're generally public. For example, I found out how to do the cname
recently by snooping on jackhill's dotfiles, since I know he's also a
JMP.chat customer and was likely using the hosted snikket instance
through them. You could find the files that my snippets come from at
/afs/hcoop.net/user/s/sm/smichel17/.public/.domtool/
The other thing is grabbing the source (from
https://git.hcoop.net/hcoop/domtool2.git) and searching through the
`lib` folder. I don't know the source well enough to decipher much from
this, but it can give you an idea of what directives are available.
easy_domain.dtl is probably the most useful one
https://git.hcoop.net/hcoop/domtool2.git/blob/HEAD:/lib/easy_domain.dtl
Also, keep us in the loop about what you figure out about DKIM! I'd
like to set it up for myself (and imagine others would, too), but,
time…
Cheers,
Stephen
