Hi,
I need clarification about a couple of aspects of SPF implementation on
which I have received two differing opinions, but from two people who are
well-versed about most Internet technical matters.
1: I have a server hosting a domain - somedomain.com
2: I run my own DNS at ns1.somedomain.com and ns2.somedomain.com
3: The domain in #1 has the mail server/MX at mail.somedomain.com
4: I host a number of other domains on the server, and host their zones in
my DNS, too.
5: The mail server in #3 is the mail exchanger/server/MX for all domains
in #4
6: Both I and other domains' users connect to the Internet through our own
respective ISPs and send email via one of two methods:
i. Through the SMTP service on my server, with a
user@theirdomain.com as their From address
ii. Through the SMTP service on their own ISP, with a
user@theirdomain.com as their From address
7: There are 30 domains, 150 diverse "From" addresses across those
domains, and 50 different ISPs people connect from.
Clarification on...
A. One person says that only in scenario 4:ii would every single ISP
through whom people connect be need to be added to the SPF records of the
individual domains and the master domain "somedomain.com"
B: The other person says that in both 4:I and 4:ii every ISP would need to
appear in the SPF
Or is it yet a different scenario?
And my question, what should the SPF be:
i. For somedomain.com
ii. For every other domain on the server
Thank you very much!
David
