Is there a space around the comma in the Domain line? I can't tell from the way this MUA formats your mail. If there is, try without it.
The issue is that "DomainB.com" doesn't appear to be in the domain list. It sees that in your From: but not in the list of domains to sign. Prior to v2.3.0, spaces weren't discarded in the Domain value which can unfortunately lead to mismatches.
"no MTA name match" means the MTA connecting to the filter didn't announce its name as "MSA", matching what you have configured.
The message would be signed if either of those were true.

Subject: DKIM - InternalHosts
Hi there -
Sorry for the length of this message, however I wanted to fit as much data in to describe the issue I am having...
I had been using DKIM-milter and switched to OpenDKIM just recently. I have 2 domains: domainA.com and domainB.com.
My server handles email for both, and I use mail.domainA.com as my outgoing server for both. (mail.domainA.com is a pointer for domainA.com).
From Thunderbird, via my home connection (sending with the outgoing smtp as mail.domainA.com) from domainB.com as the "from", I see the following:
Jan 25 22:39:59 opendkim[21561]: p0PMdtQh021667: no MTA name match
Jan 25 22:39:59 opendkim[21561]: p0PMdtQh021667: no signing domain match for `DomainB.com'
Jan 25 22:39:59 opendkim[21561]: p0PMdtQh021667: no signing subdomain match for `DomainB.com'
Jan 25 22:39:59 opendkim[21561]: p0PMdtQh021667: no signature data
Sending via my webmail, I see OpenDKIM working perfectly.
From thunderbird, via my home connection (sending with the outgoing smtp as mail.domainA.com) from domainA.com as the "from", I see OpenDKIM working perfectly. Although it does say " no MTA name match".
1.) What do I need to configure so that sending with domainB.com works?
2.) What does " no MTA name match" mean and how can I fix it?
