    Will there be a problem with your server sending for email notifications?

    Asked by besam on June 25, 2014 at 09:22 AM

    The last days, we'll get sometimes a notification, sometimes not. 
    And we're testing ourself, so we know when we send a subscription :-)

    So I'm looking how to solve, but I can't detect a "system" in the suscriptions.
    First thing I have to exclude is the sender (your e-mail server) :-)

    Thank you for contacting us.

    Looks like you have setup your email notification to use the custom smtp sender email. I also notice that one of the email recipient's email address in your email notification is invalid. Please note that you are sending the notification using your smtp server, so, if there are emails not being received, investigation should be done on your email server.

    If you notice, the recipient email on this particular email notifier is incorrect. If you want to use the email address typed in the email field of your form, you must be trying to setup an autoresponder rather than the email notifier.

    Let us know if you have other questions.

    Thanks for your replay.

    But it's the e-mail Notification named "Notification Catherine" what will provide problems and not will be received. The e-mail recipient is one of our own e-mail address in our office.

    This form with notification has worked always perfect but since a few days e-mails will not be received.
    And when sending a normal e-mail (out of Jotform) to this mailbox it works and will be received.
    Very strange....

    The notifications are still sent from our servers, but are still using your email address m*******besam@assaabloy.com as its sender.

    This setup appears as if the sender email is being spoofed by JotForm. Most likely, your server rejects the notifications because of this reason.

    There are two possible solutions to this:

    A) Add our mail server IP's and domains to your mail server's whitelist, so that the messages are not rejected

    B) Re-add the sender emails as SMTP accounts so that the emails are actually sent from your server, not ours thus increasing the chances of mail delivery

    Let us know if you would like to take option B, so we can provide you with further instructions.

    It's solved now. Thanks !

    I used one of the default Jotform addresses for the sender address. And this solved my problem.
    Thank you Jotform !
