Thanks for this helpful article Alfa. I'm trying to get my board compliant with many of these items.

One quick thing I am trying is I created a new template I called email_footer1, which contains text similar to:

_____________________________________________________________
This email was sent to $bbuserinfo[email], based on account registration.
To manage your email preferences, update your account settings at $vboptions[bburl]/profile.php?do=editoptions

Alternatively to unsubscribe, go to $vboptions[bburl]/$vboptions[contactuslink], or reply to this email with the word unsubscribe as the subject.
Mailing address: some name, someplace
Telephone: telephone
To report abuse, email abuse@yourdomain

Then I added a plugin hooked on mail_send to hopefully append the relevant info to the bottom of all e-mails sent by vbulletin?

// Add footer to outbound e-mail
eval('$message .= "' . fetch_template('email_footer1') . '";');

(You don't want to know how long I spent getting that to work, especially since I had \\ instead of // for the comment )

The DKIM looks interesting. My host doesn't let me add any fields to the domain record though so it looks like I'd need to use a different DNS to put out the info
