What would cause intermittent DomainKey-Status: failures?
- by wherestheph
Every week, we send something like a small newsletter. Sometimes, the header in the newsletter says
DomainKey-Status: bad (test mode)
Sometimes it says
DomainKey-Status: good (test mode)
All the other headers in the email are the same (besides expected time and message id differences). None of the email server configuration has changed. What would cause this problem?
