SPF records have errors.
SPF records have errors.
I found a subtle error on the SPF records for zoho.com and zcsend.com
zoho.com txt resolves to include:spf.zoho.com and include:spf2.zoho.com
the entry spf.zoho.com resolves to:
v=spf1 ip4:74.201.152.59/32 ip4:74.201.155.27/32 ip4:74.201.155.28/32 ip4:74.201.154.0/24 ip4:74.201.84.0/24 ip4:216.52.72.26/29 ~all
The last entry ip4:216.52.72.26/29 has a CIDR error. The block should be 216.52.72.24.29 to match properly CIDR
Same goes to spf.zcsend.net
the entry 74.201.84.33/27 has the same class of CIDR error: should be 74.201.84.32/27
