Summary0005173: No reverse DNS for smtp server sending bugs account info
DescriptionI noticed I didn't initially get my account activation / password email. I have this in my logs:

Dec 23 16:24:51 orbital postfix/smtpd[16949]: NOQUEUE: reject: RCPT from unknown[208.88.127.105]: 450 4.7.1 Client host rejected: cannot find your reverse hostname, [208.88.127.105]; from=<info@kali.org> to=<brandon@burn.net> proto=ESMTP helo=<smtp.kali.org>

And indeed, both auth NS'es give NXDOMAIN for this:

root@orbital:/home/vom# dig +norecurse @ns1.datanap.net -x 208.88.127.105 | grep status:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 56608
root@orbital:/home/vom# dig +norecurse @ns2.datanap.net -x 208.88.127.105 | grep status:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 1567

This is likely causing a good deal of email to be rejected.
Steps To ReproduceAttempt to create account/take action that sends an email.
