    What is your actual domain name for sending emails?

    Asked by Damien Hradowsky on February 13, 2012 at 08:31 PM

    The spam blocker we use is Postini. We have six email addresses that are linked to receive emails when a customer submits a request on our website. The request uses your form system and it works really well except, even when I put JotForm.com as an approved sender in our spam filter, it continues to be flooded to the quaratine list. My colleagues still get the emails but, it is a day later after they receive the quaratine emails. This is why I was wondering what the full domain name is or if you have any other ideas behind fixing this issue. Thank you.

    Are you able to whitelist the ip addresses of email servers? 

    We could send emails from any of the following IP addresses.,,,,

    I'm having the exact same problem. Postini needs domain names and not IP addresses. Please advise as to what your exact domains are so that I can add them to our whitelist. THANKS!!

    It did not. That was an old method that can no longer be used with our configuration. So we're still having all submissions quarantined. 

    Any other options?
