dkim-filter doesn't generate a signature with i= tag and therefore is
considered to be the default (namely @mydomain.com).

I think the problem is generated by the signing dkim-filter daemon,
which should have set [EMAIL PROTECTED] in DKIM-Signature when
following conditions are satisfied:
 - the originator address is [EMAIL PROTECTED]
 - "SubDomains Yes" is present in dkim-filter.conf
 - the selector TXT record doesn't have t=s
