Well, there are two parts of this:<br>
<br>
1 - make a decision which servers are allowed to send mail on your
behalf - this is entirely up to you. This is expressed in terms of
server names, IP addresses etc.<br>
You may decide that ONLY <these> servers may send mail or that
other servers are allowed to also send mail. One example is a
portable computer, may that use a local server to send mail or
should that be considered bogus?<br>
<br>
2 - express these decisions in an spf statement - this is where the
RFC comes into play, explaining how to interpret the statements.<br>
<br>
<br>
You need to make decision #1 yourself.<br>

I also generated the following SPF using a wizard. Let me know if
this looks correct:
<br>
<br>
teamwarfare.com. IN TXT "v=spf1 a mx a:mail.teamwarfare.com
a:mail2.teamwarfare.com ip4:66.90.73.80 ip4:216.250.250.148 ~all"
<br>
<br>
I wouldn't need an "include:" or "ptr" statement in this right? I
would told "include:" was to include OTHER domains that are
allowed to send e-mail, but then again I see some people writing
the domain again as an include. Also is PTR good to use or not?
<br>
<br>
Sten,
<br>
I read over the link but am still a bit confused.

I am inquiring about how to setup a proper SPF record? I know
there
<br>
are SPF wizards/generators available but each seem to have a
different
<br>
"opinion" of what should be included and what should not be
included.
<br>
<br>
Let me give you a scenario of my setup, and hopefully someone
can help
<br>
me out.
<br>
<br>
My domain is: test.com
<br>
My mailserver hostname is: mail.host.com which also has a
MATCHING PTR
<br>
record
<br>
mail.host.com (for example) resolves to 50.1.1.1 and 50.1.1.1
resolves
<br>
to mail.host.com
<br>
<br>
This is a STANDALONE mail server without any VIP's or load
balancing.
<br>
There is however one additional host that will send out mail
from the
<br>
domain but it wont be receiving mail, it will only be used as
an SMTP
<br>
server attached to a website automailer... It only generates
error
<br>
reports and sends them out... so technically it isn't a full
mail
<br>
server but it will be sending (outbound only) mail on behalf
of the
<br>
domain.
<br>
<br>
The additional host is: mail2.test.com which resolves to
50.2.2.2 and
<br>
there is a Matching PTR.
<br>
<br>
These are the ONLY mail servers and IP addresses that will be
sending
<br>
out mail from the test.com domain. Some websites say I should
use -all
<br>
and others say -all will cause some MTA's to reject and ~all
is better
<br>
to use even if those are the only two hosts sending out mail.
<br>
<br>
Would you be able to assist with a solid SPF record?
