Hello
Our mailserver which answers smtp queries as 'mtown.com' hosts several
other domains.
Our organization has an assigned CIDR address space of 64.204.63.128/25
- 64.204.63.255/25
Mail from our domains will only be sent from these addressess.
Would you take a look at the two example dns TXT statements and tell me
if this is the best most network efficient way to do SPF?
mtown.com. TXT
"v=spf1 ip4:64.204.63.128/25 a:dnsforyou.com a:dnsspy.com
a:gldata.com -all"
---------------------------
gldata.com. TXT
"v=spf1 ip4:64.204.63.128/25 mx include:mail.mtown.com -all"
Thanks -
George Young
