I don't think v1 supports DKIM. I'll consider upgrading to v2. 

Is there good documentation on how to upgrade from v1 to v2?

Hi!
Fritz Borgstedt: > Disable the feature. 
 To All:
Disable DoMSGIDsig ( Do Message-ID Signing ) -- [ as minimum, IMHO] is not
super-Ok solution
 
To Nikola Lazic:
 
1)
 Why OpenDKIM? 
Why not DKIM feature in ASSP v2.X ( and may be in 1.9X/1.8X) ?

0)
 
==
I send a message from server a.com as [email protected] to [email protected].
b.com has ASSP running and a.com is in localDomains.
The *incoming* emails Message-ID is modified by ASSP on b.com and as such 
passed to the MTA.
==

I.e.:  b.com has "a.com" is in localDomains?

 Add  no-LAN servers to "local*"  is  not-Super-Ok solution itself  -- use
WhiteDomain and/or WhiteList  and/or  see later about noProcessing
==
b.com is a.com's MX
==

May be best place a.com to npaddresses.txt / No Processing Addresses* / 
(noProcessing)  to ASSP files on b.com servers ?

Or IP adresses of a.com to noProcessingIPs ( No Processing IPs*) ? ipnp.txt
?
 
 
2)
 
 Try set
MSGIDpreTag ( Message-ID pre-Tag for MSGID-TAG-generation )
 
 on
a.com
 a-la
MSGIDpreTag:=seca
 
 on 
b.com
 a-la
MSGIDpreTag:=secb
 
 
 and use DKIM check/sign feature[s] in ASSP v2.X ( and [may be] turn Off
DKIM in check MTA and/or disable OpenDKIM )

Subject: [Assp-user] DKIM and Messsage-ID Change 1.9.1.8

In some instances ASSP 1.9.1.8(1.1.01) will change the original message's
Message-ID header by prefixing it with "assp." followed by an alphanumeric
string. I think this happens when a message is received from a host listed
in localDomains. I'm not sure what the purpose of the Message-ID
modification is.



If the message has been signed using DomainKeys and Message-ID is a header
included in the signature (recommended by RFC 4871 and default for OpenDKIM)
the Message-ID change will invalidate the signature. An error message in the
sendmail mail log will be created:



Jan  9 15:51:27 domain.com sendmail[10092]: [ID 801593 mail.info]
q09KpRVM010092: Milter insert (1): header: Authentication-Results:
domain.com; dkim=fail (verification failed)\n\[email protected]
header.b=ut6J4Ex+;\n\tdkim-adsp=unknown

Jan  9 15:51:27 domain.com opendkim[2943]: [ID 632817 mail.info]
q09KpRVM010092: s=mail d=other.domain.com SSL error:04077068:rsa
routines:RSA_verify:bad signature

Jan  9 15:51:27 domain.com opendkim[2943]: [ID 614597 mail.notice]
q09KpRVM010092: bad signature data



A solution is to exclude Message-ID from the signature. In opendkim.conf:
OmitHeaders Message-ID.



Is there a way to modify ASSP so this doesn't happen?
