I don't think so. At least I thought that the hot wiring that I did to my
mail server only effected /sending/ of email.
The changes I made to the DNS server would have effected /receiving/ of email.
I have successfully sent a message to the geeks at sunhelp mailing list /and/
received my copy of said message from said mailing list.
I have since resubmitted the same message
manually to sunhelp.org's SMTP
receiver (the original message is still in the outgoing mail queue:
smtp/sunhelp.org: B/W/23993316: (196 tries, expires in 2d17h) smtp; 466 (No
DNS response for host:
sunhelp.org; h_errno=0)
) to see what happens and got a DSN ack even, but the message did
not get through.
Were you sending a message to geeks at sunhelp or a different address?
It was to <rescue at sunhelp.org>. The resubmitted message eventually made
it through last Tue, Oct 20th, after a week of being held:

which I think does coincide with the revival of
mrbill.net services:

MRBILL.NET

and makes me conclude my suspicion was right.
So local hot
wiring of name resolution (which I suppose could be as easy as
adding a /etc/hosts entry rather than going through the hoops of setting up
a manipulated name server) might be good enough to get at the web pages, but
not to get the list going.
Ya ... email tends to be more reliant on DNS. At least unless you explicitly
tell it to not use it for specific domains. And that's exactly what I did. I
hard (hot) wired email routing so that email for
sunhelp.org goes to
ohno.mrbill.net, which is resolvable do to my DNS hot wiring (forwarders).
I wish it was the case. The admin of
linux-mips.org, a friend of mine,
has vanished since the outbreak of the COVID-19 pandemic in Europe last
March -- I do hope nothing wrong has happened to him and he does surface
sometime.
Anyway, he's the only one who can remove a stale /etc/hosts entry here
for
vger.kernel.org, which prevents me from posting to any Linux kernel
mailing lists hosted there unless I resort to some horrible hacks, which
in turn tend to randomly break sending e-mail elsewhere. Sigh...
