I've got this SPF rejection and I'm still confused as to exactly what gets trigerred. Obviously the message is rejected before I get to see any headers that would give me a better clue. The envelope sender domain SPF does include this IP 64.74.157.52 but the From: domain does not so I think my question is, that with my bofh SPF rules, how come BOFHSPFMAILFROM didn't give me a pass?Feb 9 07:47:38 mail courieresmtpd: error,relay=::ffff:64.74.157.52, from=<SRS0=MnWw=VF=morningstar.com=help...@bounce2.pobox.com>: 517 SPF fail help...@morningstar.com: Address does not pass the Sender Policy Framework courier-mta 0.60.0 opt BOFHSPFHELO=pass,none,neutral,softfail,unknown,error opt BOFHSPFMAILFROM=pass,none,neutral,softfail,unknown,error opt BOFHSPFFROM=pass,none,neutral,softfail,unknown,error,mailfromok opt BOFHSPFTRUSTME=1 First the From: domain... ~ dig +short txt morningstar.com "v=spf1 a:spfmailer.morningstar.com -all" ~ dig +short a spfmailer.morningstar.com 66.35.231.16 66.35.231.15 216.228.234.30 216.228.233.9 216.228.233.10 216.228.228.165 216.228.228.164 216.228.228.163 216.228.228.162 216.228.228.161 216.228.228.160 216.228.224.50 216.228.224.34 216.228.224.33 216.228.224.32 210.193.131.12 12.43.226.3 66.35.231.18 66.35.231.17 No 64.74.157.52 above.

The only thing I can think of would be a transient DNS lookup failure for pobox.com. mailfromok is accepted only if the SPF lookup on the MAIL FROM resulted in pass.
A transient DNS lookup failure results in an SPF softfail result, rather. I think this is probably wrong; mailfromok should be accepted if the SPF lookup resulted in softfail, as well…
