Too many records in txt

Hi there.

I was trying to add some domiankeys to my TXT records, and it is now longer
than the allowed length because of all of my SPF records.

I use GoDaddy total MX and Domain manager to setup my TXT records. For spf,
I have entries that look like this:

@ v=spf1 mx ip4:192.168.1.101 -all
subdomain1 v=spf1 mx ip4:192.168.1.102 -all
subdomain2 v=spf1 mx ip4:192.168.1.103 -all
subdomain3 v=spf1 mx ip4:192.168.1.104 -all
subdomain4 v=spf1 mx ip4:192.168.1.105 -all
subdomain5 v=spf1 mx ip4:192.168.1.106 -all
subdomain6 v=spf1 mx ip4:192.168.1.107 -all
subdomain7 v=spf1 mx ip4:192.168.1.108 -all

(I put in generic ip addresses here but am using real ones in my config.)

I am not sure how to write the spf to include all of the subdomains with
unique ip addresses. Would this be equivalent?

@ v=spf1 mx ip4:192.168.1.101/28 -all

Thanks!

Mark

Hmmm...each SPF record (subdomain) is its own TXT record, they
aren't combined.

This would apply to the main domain and not subdomains. You
could use the same for each, sure, though that would allow each to send
mail for the others.

Your examples use "mx" and a private IP address range...assuming
you're obscuring the IP, is it still different than the MX record for
each domain? If not, just list the IP.
