If you can specify the servers  with ip addresses then that's all you
need.

I usually choose soft fail because a user might decide to use a mobile
device for email.

Waitman,

Fair enough statement.

I also generated the following SPF using a wizard. Let me know if this 
looks correct:


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"


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?

Question regarding SPF records

[Jonathan Vomacka]

I am inquiring about how to setup a proper SPF record. I know there are 
SPF wizards/generators available but each seem to have a different 
"opinion" of what should be included and what should not be included.


Let me give you a scenario of my setup, and hopefully someone can help 
me out.


My domain is: test.com
My mailserver hostname is: mail.host.com which also has a MATCHING PTR 
record
mail.host.com (for example) resolves to 50.1.1.1 and 50.1.1.1 resolves 
to mail.host.com


This is a STANDALONE mail server which will receive and send email 
without any VIP's or load balancing. There is however one additional 
host that will send out mail from the domain but it wont be receiving 
mail, it will only be used as an SMTP (outbound only) server attached to 
a website automailer which is on a seperate webserver... It only 
generates error reports and sends them out... so technically it isn't a 
full mail server but it will be sending (outbound only) mail on behalf 
of the domain.


The additional host is: mail2.test.com which resolves to 50.2.2.2 and 
there is a Matching PTR.


These are the ONLY mail servers and IP addresses that will be sending 
out mail from the test.com domain. Some websites say I should use -all 
and others say -all will cause some MTA's to reject and ~all is better 
to use even if those are the only two hosts sending out mail.


Would you be able to assist with a solid SPF record?
