Guys,
I have seen some unexplained behavior since upgrading to MSQ 1.996 a couple
of days ago. Specifically, my log shows two recent SPF Fail's, but the
domains in question do not have SPF records:
http://www.dnsstuff.com/tools/lookup.ch?name=atlaswebmail.com&type=TXT
http://www.dnsstuff.com/tools/lookup.ch?name=Lamdforms.com&type=TXT
This is a known "feature" of M:S:Q 1.996. Any time a host does not
exist (not just lacking a TXT record, but an NXDOMAIN), the SPF check
fails. This is allowed under the SPF spec and was a change that was
discussed right before the spec went to the IETF. Meng said that this
would be changed back in 1.997.
This issue was discussed a fair amount about 2 weeks ago under the
subject of "A HELO Question".
