Morning all,
I need some help on setting up my SPF.
I have 5 servers that can send email for my organization.
2 internal Exchange servers, and 3 DMZ based content filtering mail
servers.
only one of the 5 servers is set up as an MX record.
I also have 3 ISP based mail servers that can host mail for me if there
is a problem with my organizations mail servers (they do not send email
for us, just host mail) and these do have MX records.
What would my SPF setup look like ?
I take it using the "v=spf1 mx -all" would not fit the necessary
settings ?
Would it be better to set up using the external IP addresses of each
server ? In this case, what would the string look like if the servers
addresses are for eg - 10.1.1.1, 10.1.1.3, 10.1.1.17, 10.1.2.45,
10.1.2.9 (obviously they have Internet based IP addresses so this is
just an example for the setup).
Any assistence would be greatly appreciated.
