Subject: [spf-discuss] Survey: When does SPF cause legitimate email to
be rejected?
Looking through the SPF-Help RT reports, it looks like the roaming
user problem is actually roaming user problem is the most frequent,
but I haven't studied the reports closely enough to be sure.
The bulk of these are actually registrar/DNS provider/domain host published
record on behalf of the domain owner without talking to them and put -all at
the end. Mydomain.com's decision to do this has had a very big impact on
the number of complaints we get.
Yes, I guess I should have been clearer. I knew that this was a
problem, but I guess I'm trying to find out what actually is causing
these emails to fail.
The biggest category that I've seen that would have to go into "Other" is
misconfigured/buggy SPF checking. It's also the most frustrating because
about all I can say is that you mail should have been accepted. IIRC, this
is usually a matter of receivers not realizing that they are rejecting
results other than Fail or doing post SMTP checking and checking the wrong
IP address.
Interesting. I guess I had forgotten about post-SMTP checking. Good
point.
