Below is a table of SPF/DKIM/DMARC statuses over the past 30 days on our inbound MX servers (umn.edu and several *.umn.edu domains). Note that we employ a DMARC policy of p=reject; also note that we have split our dmarc 'fail' status into three categories:
*fail* indicates a DMARC failure where the sender domain had a policy of p=none *quarantine* indicates a DMARC failure where the sender domain had a policy of p=quarantine *reject* indicates a DMARC failure where the sender domain had a policy of p=reject *dkim* *spf* *dmarc* *count* *pct* *description* pass pass pass 52954883 73.62% Accepted pass pass none 11792134 16.40% Accepted; no “From:” domain fail pass pass 2529364 3.52% Accepted: Passed based solely on SPF alignment pass pass fail 1155823 1.61% Accepted, but alignment failed for both SPF and DKIM fail pass none 1131260 1.57% Accepted; no “From:” domain pass fail pass 991879 1.38% Accepted: Passed based solely on DKIM alignment pass none pass 200502 0.28% Accepted: Passed based solely on DKIM alignment fail pass fail 191296 0.27% Accepted: Failed, no DMARC policy pass none none 190378 0.26% Accepted; no “From:” domain fail none fail 134941 0.19% Accepted: Failed, no DMARC policy fail none none 134144 0.19% Accepted; no “From:” domain pass fail none 102386 0.14% Accepted; no “From:” domain fail fail none 88609 0.12% Accepted; no “From:” domain fail none reject 65894 0.09% Rejected (missing or bad DKIM) fail fail fail 58133 0.08% Accepted: Failed, no DMARC policy fail fail reject 49305 0.07% Rejected (missing or bad DKIM) pass pass quarantine 36596 0.05% Marked as spam (lack of alignment) pass none fail 16517 0.02% Accepted: Failed, no DMARC policy pass fail fail 15971 0.02% Accepted: Failed, no DMARC policy pass pass reject 15923 0.02% Rejected (lack of alignment) fail pass quarantine 14532 0.02% Marked as spam (lack of alignment) fail pass reject 13484 0.02% Rejected (lack of alignment) pass tempfail pass 10640 0.01% Accepted: Passed based solely on DKIM alignment fail tempfail none 10543 0.01% Accepted; no “From:” domain fail fail quarantine 9149 0.01% Marked as spam fail none quarantine 5437 0.01% Marked as spam pass tempfail none 1226 0.00% Accepted; no “From:” domain pass fail reject 1179 0.00% Rejected (lack of alignment or DKIM signature match) pass fail quarantine 926 0.00% Marked as spam (lack of alignment) pass none reject 630 0.00% Rejected (lack of alignment or DKIM signature match) fail tempfail reject 547 0.00% Rejected (lack of alignment) fail tempfail fail 537 0.00% Accepted: Failed, no DMARC policy pass none quarantine 265 0.00% Marked as spam (lack of alignment) pass tempfail fail 106 0.00% Accepted: Failed, no DMARC policy pass tempfail reject 10 0.00% Rejected (lack of alignment or DKIM signature match) fail tempfail quarantine 9 0.00% Marked as spam pass tempfail quarantine 1 0.00% Marked as spam (lack of alignment)
