Dear those who might know about dkim-milter,
The DKIM-Filter I run occasionally returns these key retrieval failure
messages, and then rejects the email.
I am trying to work out whether this is,
a misconfiguration problem with the sender's DKIM entry in DNS,
a time-out from my server to the DNS
a misconfiguration on my server.
Some messages from the postfix log follows:-
Feb 9 14:08:05 srv1 dkim-filter[6967]: 0F40884146: key retrieval failed
Feb 9 14:08:05 srv1 postfix/cleanup[19030]: 0F40884146: milter-reject:
END-OF-MESSAGE from smtp143.junkemailfilter.com[69.50.231.143]: 4.7.1
Service unavailable - try again later; from=<bounce(_at_)couchsurfing(_dot_)org>
to=<niceuser(_at_)klunky(_dot_)co(_dot_)uk> proto=ESMTP
helo=<junkemailfilter.com>
Again, if someone would point me in the right direction, then perhaps I
can work out what to test and then mend.
This mightn't be the right list. I'm still looking for the right one,
but it is certainly related.
Best regards, S
