It is possible to make SPF not do this checking and allow
sendmail do it?
As per the specs, rejecting is up to the MTA:
2.5.6 TempError
A TempError result means that the SPF client encountered
a transient error when performing the check.
OK ... 'TempError' results from a 'transient error'.
I suppose that a 'transient error' is some error condition
that has caused a failure and cannot be corrected, but will
not be an error condition at some future time.
Right?
I don't see how it could be possible for the SPF client
to determine NOW that the error will be corrected in the
FUTURE?
The terms 'TempError' and 'transient error' bother me
by being too imprecise.
Perhaps 2.5.6 should be called 'Incomplete'. As an
example, that could occur if the SPF client was unable
to get any DNS response.
Could we consider this rewording?
2.5.6 Incomplete
An Incomplete result means that the SPF client
encountered an error that prevented it from
performing the check. Checking software may
be configured to accept or temporarily reject
the message. If the message is rejected during
the SMTP transaction for this reason, the
software SHOULD use an SMTP reply code of 451
and, if supported, the 4.4.3 DSN code.
