Ho un dubbio sulla firma con DKIM.
Mandando un messaggio a check-auth@verifier.port25.com ottengo tra i risultati
DKIM check = pass
ma anche
0.1 DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid
0.0 T_DKIM_INVALID DKIM-Signature header exists but is not valid
tra i check effettuati da SpamAssassin.
Potrebbe essere un problema di SpamAssassin lato ricevitore, o un problema lato mio...
Come fare a essere sicuri?

NOTE: DKIM checking has been performed based on the latest DKIM specs
(RFC 4871 or draft-ietf-dkim-base-10) and verification may fail for
older versions. If you are using Port25's PowerMTA, you need to use
version 3.2r11 or later to get a compatible version of DKIM.

==========================================================
Explanation of the possible results (from RFC 5451)
==========================================================
SPF and Sender-ID Results
=========================
"none"
No policy records were published at the sender's DNS domain.
"neutral"
The sender's ADMD has asserted that it cannot or does not
want to assert whether or not the sending IP address is authorized
to send mail using the sender's DNS domain.
"pass"
The client is authorized by the sender's ADMD to inject or
relay mail on behalf of the sender's DNS domain.
"policy"
The client is authorized to inject or relay mail on behalf
of the sender's DNS domain according to the authentication
method's algorithm, but local policy dictates that the result is
unacceptable.
"fail"
This client is explicitly not authorized to inject or
relay mail using the sender's DNS domain.
"softfail"
The sender's ADMD believes the client was not authorized
to inject or relay mail using the sender's DNS domain, but is
unwilling to make a strong assertion to that effect.
"temperror"
The message could not be verified due to some error that
is likely transient in nature, such as a temporary inability to
retrieve a policy record from DNS. A later attempt may produce a
final result.
"permerror"
The message could not be verified due to some error that
is unrecoverable, such as a required header field being absent or
a syntax error in a retrieved DNS TXT record. A later attempt is
unlikely to produce a final result.
DKIM and DomainKeys Results
===========================
"none"
The message was not signed.
"pass"
The message was signed, the signature or signatures were
acceptable to the verifier, and the signature(s) passed
verification tests.
"fail"
The message was signed and the signature or signatures were
acceptable to the verifier, but they failed the verification
test(s).
"policy"
The message was signed but the signature or signatures were
not acceptable to the verifier.
"neutral"
The message was signed but the signature or signatures
contained syntax errors or were not otherwise able to be
processed. This result SHOULD also be used for other
failures not covered elsewhere in this list.
"temperror"
The message could not be verified due to some error that
is likely transient in nature, such as a temporary inability
to retrieve a public key. A later attempt may produce a
final result.
"permerror"
The message could not be verified due to some error that
is unrecoverable, such as a required header field being
absent. A later attempt is unlikely to produce a final result.
