Hi, I observed some strange behaviour with our courier server when it comes to SPF checks. I think this particular SPF check should not fail, but perhaps I am wrong, please enlighten me:
Courier is configured to do SPF check in this way: BOFHSPFMAILFROM=pass,none,unknown,softfail,neutral To me that means that courier checks during the "MAIL FROM" command the sender domain and it should fail only if the "-all" statement is used in the SPF record. Now I see in the maillog problem with mails coming from osb.org . Mails are temporarly rejected with a "417 DNS MX lookup failed" error. The SPF record for osb.org is --- "v=spf1 mx mx:smtpcluster.computing.csbsju.edu ip4:152.65.184.22 ip4:152.65.184.23 ip4:152.65.184.40 ip4:152.65.184.46 ip4:152.65.184.52 ip4:152.65.184.137 ~all" --- Well for me with this configuratin any SPF check on osb.org should never fail, but only generate some additional SPF headers in the mail, even with corrupted SPF records or non-resolving MX addresses. -- Georg ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
