I thought it was related to the sending domain, which it was, but I later learned one of the includes in our domain was also apparently expanded, and caused our SPF record to temporarily exceed the 10 DNS query limit, confusing the entire situation. > it's hard to explain why it does not work if you don't provide proper info. I understand. Thank you for being patient. Thanks, Alex
