What should I do

Fix too many SPF lookups

Get the DNS-querying terms down to 10. ip4 and ip6 do not query DNS at evaluation time, so a host written as an address does not spend one of the 10.

• Count include, a, mx, ptr, exists, and redirect. Nested includes count, because the limit covers lookups those mechanisms cause.
• Remove a sender that no longer sends. Each include you drop gives the count back.
• Do not publish a second SPF record to hold the overflow. Two v=spf1 records are a permerror of their own.
