I understand your reasons and got used to it. Still fun. :)

I made a summary:
https://sourceforge.net/p/whonix/wiki/Remailer/
(Mixminion is not listed there, but most remailers run Mixmaster,
Cypherpunk and Mixminion at the same time. Since Mixminion isn't ready
yet (there own statement) and Mixmaster has too few users, not too much
has to be learned about remailers.
> Is Mixmaster the best current solution?
No. Refer to mixmaster as a tool to send mails. Ignore any mixmaster
anonymity giving aspects. Anonymity is provided by Tor. And this is
about running a mail sending tool over Tor.

There are too few users.
I consider it off topic here, but anyway, Roger Dingledine made very
nice comparison:

Perhaps Mixmaster can be convinced to talk to it. I don't know. Further
implementations (Mixfaster, Mixminion) will not require an extra
mailserver anymore.

Unfortunately, not.

It is my understanding, that Mixmaster itself doesn't, but Postfix does.
It looks like the standard way for an MTA to resolve the MX for a given
mail server domain. I haven't found a way to disable it.
I tried k54ids7luh523dbi.onion (remailer.frell.eu.org) or
gbhpq7eihle4btsn.onion (snorky) as relayhost in /etc/postfix/main.cf,
but still keep getting "status=deferred (Host or domain name not found.
Name service error for name=gbhpq7eihle4btsn.onion type=MX: Host not
found, try again)".
> Can't we get rid of the need at the root?
I don't know. Either getting the hidden mailservers to work, somehow
deactivating need for it, patching the MTA (beyond my abilities) or... I
really don't know. At the moment it's the biggest obstacle.
