Ok so if I understand you correctly the problem is I am sending mail as root_at_marlborosurvey.net from root_at_mail.marlborosurvey.net and if I want to continue to send like that I have to disable sendmail's masquerade feature? Is that correct?

The error in the log is fine; it just means it didn’t find “mail.marlborosurvey.net”
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.

 

The signature failure is probably caused by you using sendmail’s
“MASQUERADE” feature. Your signing filter sees “mail.marlborosurvey.net”, but
I can tell from the reply that what sendmail.net sees is just “marlborosurvey.net”.
So what gets signed and what gets received aren’t the same, so the signature will
fail.

 

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

By the way in case you where wondering what
I did to the opendkim.conf file I just set "subdomains yes".
