I'm wondering how do I set up my DKIM for the SMTP server when I have the site located at a shared hosting company? The site is located at bluehost.com and regular mail (i.e. mail sent from outlook and thunderbird) is sent using the mail.ultratrust.com and I think *.bluehost.com as the SMTP servers. Bulk (double opt-in) will come from http://smtp.com
from a software that is hosted at http://emailmarketingservicesco.com
I read instructions on setting it up if one hosts their own linux VPS or dedicated server but the mail domain is hosted at bluehost.com.
Thanks. Any help is appreciated.
