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?
