First of all you should avoid using multiple TXT parts although in
practice the result would be the same as you're careful enough to
add spaces as first symbol of next part. But bigger problem is that
you need to think if there is a need to use both mx and list every
system by ip address. One of the MXs - "mx:beachcomp" is also not quite
valid (or rather not what you inteded). I also think you need to get
familiar with network concept called "summarization" (as it applies to
ip addresses at least). Te following would for example provide exactly
the same information and is much shorter:
"v=spf1 a mx ip4:69.93.89.98/31 ip4:69.93.89.100/31 ip4:69.93.89.102
ip4:69.56.240.80/29 ip4:70.84.106.132/30 -ip4:70.84.106.143
ip4:70.84.106.136/29 ip4:67.18.13.202/31 ip4:67.18.13.204/31
ip4:67.18.13.206 mx:mail.beachcomp.com -all"
