Hi,
running latest version of dkim-filter on two systems:
System 1 (MX value 20): running Postfix 2.6.5 and latest version of
dkim-filter on Ubuntu server:
dkim-filter: Sendmail DKIM Filter v2.8.3
Compiled with OpenSSL 0.9.8g 19 Oct 2007
Supported signing algorithms:
rsa-sha1
rsa-sha256
Supported canonicalization algorithms:
relaxed
simple
Active code options:
_FFR_DKIM_REPUTATION
_FFR_MULTIPLE_SIGNATURES
_FFR_PARSE_TIME
_FFR_STATS
System 2: (MX value 10): running Sun Java System Messaging Server 7.0
update 3, with latest version of dkim-filter on RedHat EL 5:
dkim-filter: Sendmail DKIM Filter v2.8.3
Compiled with OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008
Supported signing algorithms:
rsa-sha1
rsa-sha256
Supported canonicalization algorithms:
relaxed
simple
Today I discovered that dkim-milter rejected messages, while I have (as
far as I know) no configuration settings that would explain this rejection.
AFAICS there are three settings in dkim-filter.conf that could make a
message be rejected:
ADSPDiscard
ADSPNoSuchDomain
RequiredHeaders
Default for all of them is 'no' which means: do not reject. In my
configuration I did not explicitely define them, so they should not be
responsible for the reject action (correct?).
The two most recent log entries on system 1 are:
Dec 16 23:11:09 lynx postfix/cleanup[21219]: A600B70395: milter-reject:

The most recent log entries on system 2 are:

([unknown] [84.241.128.220]) 33:451 4.3.2 Milter rejected message
Please note: the timestamps do correlate, although it seems they do not;
one of the systems is running NTP and the other does not yet).
What can dkim-milter make reject a message in this way?
