Too many included lookups (13)

Hi all,

I’m getting “Too many included lookups (13)” error when I do a spf lookup “mxtoolbox” How can this this be resolved.


Hi Larry,

Thanks for reaching out, your SPF record can only include a maximum of 10 include lookup statements. If you remove a few this should fix your issue. Also here is a link for some more resources,
