Hi, list!
Due to a new installation of my vServer I installed Exim 4.75 (from Source).
The Server has Ubuntu 10.04 Server as OS.
I compiled Exim with DKIM support and I configured it.
It works and I can sign outgoing mails and check incoming mails.
But I have a very strange problem, if the incomining E-Mail comes from a
mailing-list server.
For example, if a get an E-Mail from this mailing list and the sender signs the
E-Mails, I can see in the exim_mainlog:
2011-04-15 13:17:55 1QAh2B-0004Yg-Hl DKIM: d=<domain> s=XXXXX c=relaxed/relaxed
a=rsa-sha256 [verification failed - signature did not verify (headers probably
modified in transit)]

<lucabert@???> R=localWrite_gw T=address_file
2011-04-15 13:17:56 1QAh2B-0004Yg-Hl Completed
I write in the received E-Mails some X-headers:
X-DKIM-Status: fail
X-DKIM-Domain: <Domain>
X-DKIM-VerifyReason: signature_incorrect
Now, as I know, DKIM (and DomainKey before) should solve the problem of a
forward, which can fail with SPF.
Could someone say me, why I get these errors?
Thanks a lot!
