I introduced "spfmilter" and began to have my users be rejected, when all
they
were trying to do was connect to our SMTP server to /inject/ mail. The SPF
check should not affect that, I thought.
SPF should only be checked on incoming mail, not outgoing mail.
It sounds like you are also checking it on outgoing mail.
Where is the best, most thorough description of the syntax and semantics of
the TXT record?
This has nothing to do with the txt record.
You are (or: should be!) verifying that only local users can send
mail to others (or else you would be an open relay).
Here you separate your users from the rest of the world. Do the
same for SPF.
