<offtopic>

Sorry for the offtopic message, but I'm wondering if this is happening to
just me or everyone.

I haven't been getting M100 list messages for a while, but found some in my
spam folder with a warning that the mail was suspicious because it had not
been authenticated. Both Yahoo and Google started requiring DMARC+SPF+DKIM
authentication recently. I notice that bitchin100.com has SPF but no DMARC
or DKIM records
<https://easydmarc.com/tools/domain-scanner?domain=bitchin100.com> in its
DNS.

I think setting up DKIM and DMARC should be something dreamhost should be
able to do for bitchin100 with some automated procedure, but I do not know.

If it has to be done manually, setting up DMARC should be easy using a
generator
<https://dnschecker.org/dmarc-record-generator.php?query=bitchin100.com>
which will output something like:

*Type:*  TXT
*Host:*  _dmarc.bitchin100.com
*Value:*  v=DMARC1; p=none; rua=mailto:[email protected]

However, adding DKIM manually
<https://easydmarc.com/tools/dkim-record-generator> may be trickier as I've
not yet had to do that. If the mailing list (mailman) is running on a
Debian or Ubuntu host, then one could install OpenDKIM
<https://tecadmin.net/setup-dkim-with-postfix-on-ubuntu-debian/>.
