Would it be possible for you to replace the following mechanisms
with their IP4 equivalents? They appear to be under your control:

- a
- mx
- mail.ashtonwoodshomes.com

With these changes, your record's DNS cost would drop from 11 down to 7.

spfcompile shows the following record as equivalent:

    "v=spf1 ip4:209.91.136.161/28 ip4:216.191.52.64/27
    216.191.52.70 216.191.52.6/31 ptr -all"

I'm sorry... a correction is needed. There are still some bugs in spfcompile. The equivalent record should read:

    "v=spf1 ip4:209.91.136.161/28 ip4:216.191.52.64/27
    ip4:216.191.52.70 ip4:216.191.52.6/31 ptr
    include:rogers.blackberry.net include:blackberry.net
    include:rogers.com include:vianet.ca include:bellnet.ca -all"
