Hello all,
I run a fairly small mail server and have been trying to get DKIM to
work. I have it working most of the way working except for one item
which has me stumped.
All of the message I send fail the body hash, and I am not sure how that
can be. I am not, I believe doing anything to them outbound that would
cause the message to change.
When I send a message to the wonderful port25.com verifier (and, yes
others - including checking through my gmail) I end up with something
like this the below.
I have enabled "FixCRLF yes" in my .conf file just be sure it was
nothing related to line feeds.
I do verify that the outbound messages appeared to be tagged properly:
_Jul 26 20:42:44 ns1 opendkim[18206]: t6R0giTH019226:
verifier.port25.com [38.95.177.125] not internal_
_Jul 26 20:42:44 ns1 opendkim[18206]: t6R0giTH019226: not authenticated_
_Jul 26 20:42:44 ns1 opendkim[18206]: t6R0giTH019226: DKIM verification

_Jul 26 20:42:44 ns1 sendmail[19226]: t6R0giTH019226: Milter insert (1):

key) header.d=port25.com header.i=auth-results_at_verifier.port25.com

_I do run Mailscanner and Spamassassin but I do not think anything is
happening outbound (i.e. Mailscanner watermarks are turned off, etc). _
_Any thoughts or hints would be greatly appreciated. _
