    emails failing to be delivered

    Asked by manatro on January 05, 2017 at 03:02 PM

    I have 2 forms that are not coming through on our Microsoft domain email addresses.  I was working a few days ago and now it isn't.  I checked the blocked email addresses in email settings and the email address is not blocked.  I added a new email to the recipients and it isn't going through to that email either.  Any suggestions?

    I checked our email logs for the address in your form and they have indeed been failing.  It looks like your address was rejecting the emails as spam.  When enough were rejected, it resulted in your address being placed on our bounce list to prevent further rejected emails.  Here is the specific error message:

    Reason(s) : smtp; 550 5.7.606 Access denied, banned sending IP

    I removed your address from the list and the notifications should attempt to send once again.  For more information on how to prevent this from happening again in the future, please see the following guide:

    If you believe further addresses are on the list, you can remove them from your end:

    Your email provider has blacklisted our sending IP and it is resulting in your addresses rejecting emails from our services.  You can have your email provider whitelist our sending IP's:

    However, they are constantly changing.  If you would like to continue using those addresses as the recipient address for your notifications, you may need to set up your notification to be sent from your own address via SMTP:

    I changed the email address it is sending to to a Gmail account.  It is still not working.

    Since your emails are sent conditionally, you would need to update the conditions:

    Change the recipient address for your conditions to your Gmail address and you'll be all set.
