    JotMails IP addresses: is there a CIDR block that we can white-list from the "@formresponse.com" domain?

    Asked by Chris Lowe  on July 26, 2016 at 05:51 PM

    The messages that our email gateway is rejecting are not from any of the IPs/domains you have listed on your white-list help page.  They are coming from:

    152.160.234.223   srv89.formresponse.com

    152.160.202.203   srv48.formresponse.com

    etc

    So we are trying to determine what this is.  Can you assist?

    Thank you,

    That does seem to be not from our whitelist page. However, we do have noreply@formresponse.com as a sender email. May I ask for the account username where you encountered an issue with the email notifications? This could help us check the issue further and identify why your email gateway is rejecting that domain. I will wait for your response.

    Yes, that information belongs to us.

    We offer non-branded sender email noreply@formresponse.com as an alternative for noreply@jotform.com to the users who do not wish to use or see jotform domain. Both should work just fine.

    You can also switch between these emails in your email notification under the advanced tab.

    Feel free to add them to your whitelist so emails coming from that address will not be rejected by your email service provider.

    Thanks!

    We do have the CIDR block, let me consult with our second level to see if they can provide us that information. You will be updated via this thread.

    We will have to wait for any news from our developers on this issue. I will contact them again to see if they can provide us with the CIDR block. If there is any news, we shall let you know on this thread. Thank you.
