SPF and TXT blowing my mind....
I used to be good at this years ago. It appears I can handle, mx, cname, a
etc, but this SPF/TXT stuff is throwing me for a loop

So, I have all my MX records set up, all through google. I poked around the
web and read it would be a good idea to add a TXT record as:

v=spf1 include:_spf.google.com ~all

not really knowing what it means.

What do I set up for my domain? SPF? TXT? and what would be the format of
each?


SECOND,

Now I have a web application that needs to send out email from its local
SMTP server. It is a strictly internal SMTP relay server sending to any
domain on the internet.
What SPF/TXT/MX records do I need to set up for it?

Thanks for your patience and help..... I have read some documentation but
being out of DNS for a while, it didn't quite sink in and I just need to
make a couple of edits to get by form now.

IF you use GOOGLEMAIL to send email from your domain,
You need to include their mail servers:

include:aspmx.googlemail.com

If you do not send email from/through googlemail, then you do not need to include that in your SPF TXT record.

RE: SPF and TXT blowing my mind.... [ In reply to ]
You haven't provided enough information for anyone to help you. SPF
(published as either a record type SPF (99) or as record type TXT or both)
is meant to tell the world what servers are allowed to send mail for your
domain. Ultimately, a receiving server should be able to check the IP of
whatever server just handed it an incoming message (the sending server)
which claims to be from your domain against your domain's Sender Policy to
verify that it (the sending server) is allowed to do so. So far, we don't
even know if you have a domain, much less what it is and how it sends mail.
If you're setting up MX records through Google, we might assume you are
registering a domain through Google and sending and receiving mail through
Google. Is that the same domain as the web application? Is it hosted at
Google, or somewhere else? By "internal SMTP relay" do you mean a server on
a private network mapping to a leased public IP, or a server on a fixed
public IP?
