    My SMTP configuration does not work once again?

    Asked by DanskTennisFond on May 18, 2017 at 07:32 AM



    We still get problems with our SMTP-configuration everytime you make a system-upgrade. Problems occured around februar 12., march 30. and now again may 8. As we recieve many submissions it´s hard work to edit and resend these.

    As everything works fine at all other times I don't think there should be a port-problem in the SMTP config.

    Thank you for reporting us.

    When I checked your e-mail notification setting, I found out that your sender e-mail is set to noreply@jotform.com

    This is probably due to the fact that our system changed it to this after your SMTP failed. However, when I checked your sender e-mail, I found in the bounce list. The reason is specified at following screenshot. 

    I removed it from the bounce list and you will be able to receive notification after that. To prevent e-mail bouncing issue which also failed your SMTP, we strongly suggest you to whitelist our IP addresses.

    On the other hand, I'm escalating this SMTP failure situation to our back-end team for a further investigation.
