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?

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 ) Best regards, Victor Miasnikov Blog: http://vvm.blog.tut.by/ P.S.

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.

In opendkim.conf: OmitHeaders Message-ID. Is there a way to modify ASSP so this doesn't happen?
