The error in the log is fine; it just means it didn’t find “”
in the Domain list. Then it tested Subdomains and got a match, which is why
the second line went away and the mail is now signed.

You need to turn off masquerading, or generate mail with a From:
that’s in the main domain, not in the “mail” subdomain.
