    spam filter issues with how you send mail

    Asked by paramountsecurity on September 07, 2011 at 05:40 AM



    we had some problems with mail from jotform going into spam. You told us to change the forms to send as noreply@jotform.com and then whitelist them which we did. They have worked fine until recently but suddenly started getting stopped. when we investigated you are now sending as another domain name- (yang.interlogy.com) although the forms are set to send as noreply@jotform.com.

    why is this?

    We use at least three mail servers that are load-balanced for optimum performance. The mail server with domain yang.interlogy.com is just one of them.

    Please add these IP addresses and domains on your whitelist to prevent your forms' notifications from getting flagged as spam:


    We hope this solution helps solve your issue. Thank you very much for your continued patronage.
