How do you turn domain names into email addresses? eg. if you have
a.b.c.d, is the email a@b.c.d or a.b@c.d or a.b.c@d?

It's a@b.c.d. The mapping is explained in Section 8:

The DNS encodes the <local-part> as a single label, and encodes the
<mail-domain> as a domain name. The single label from the <local-part>
is prefaced to the domain name from <mail-domain> to form the domain
name corresponding to the mailbox. Thus the mailbox HOSTMASTER@SRI-
NIC.ARPA is mapped into the domain name HOSTMASTER.SRI-NIC.ARPA. If the
<local-part> contains dots or other special characters, its
representation in a master file will require the use of backslash
quoting to ensure that the domain name is properly encoded. For
example, the mailbox Action.domains@ISI.EDU would be represented as
Action\.domains.ISI.EDU.
