Help with SPF

[Redkite]

Mailtraq version 2.18.270.3434

Hi

I need help with our SPF records for use with mailtraq.

The domain is nicolandandrew.com and we have in effect two ip addresses that Mailtraq can use. The second one only tends to be used if the first broadband line goes down (which it used to do a lot).

The router specifies which line connects to Mailtraq and failsover to the second line.

We use mt.nicolandandrew.com as the primary mailserver and we also now use mailkeep to act as a backup.

mt1.nicolandandrew.com is pointed to the second ip address if the first is unavailable (this is probably not ideal as i suspect it will not resolve if Mailtraq is not connected at the time).

So question is how best to deal with this and based on that how to set the spf record.

I also noticed when i do an SMTP test it says >Warning - Reverse DNS does not match SMTP Banner< and it also says it does not support TLS which i do have turned on in Mailtraq.

Any help much appreciated.
