We'll need it to send emails. Postfix? Do we even want to do our own emailing stuff?

Added "v=spf1 a mx -all" as a TXT record for thesourcecoffee.com

Installed exim4 and did: sudo dpkg-reconfigure exim4-config choosing internet site; mail is sent and received directly using SMTP and defaults for the rest

Had to put:

net.ipv6.conf.all.autoconf=0 net.ipv6.conf.all.accept_ra=0

in /etc/sysctl.conf and do a:

sudo sysctl -p /etc/sysctl.conf

to disable ipv6 because Google was marking as spam still: Received-SPF: fail (google.com: domain of nick@thesourcecoffee.com does not designate 2600:3c01::f03c:91ff:fe70:7dcc as permitted sender) client-ip=2600:3c01::f03c:91ff:fe70:7dcc;

I could have just put the ipv6 address in the spf1 TXT record, but that would require having eric updating DNS again and waiting for TTL expiration. Creating an issue for future reference.
