Email Address Blocked?Asked by kenfoster4316 on March 13, 2017 at 05:22 PM
My client is not getting his form-fill submissions.
Can you please check and see if an email address is being blocked for me please? The email address is email@example.com.
firstname.lastname@example.org was IN the bounce list
Reason(s) : smtp; 571 Email from 184.108.40.206 is currently blocked by Verizon Online's anti-spam system. The email sender or Email Service Provider may visit http://www.verizon.net/whitelist and request removal of the block. 160830
I had removed the email id from bounce list. You can remove the same by yourself by following the instructions provided at :
This usually happens when the messages are rejected by your email service provider. Our servers will try several times to deliver the messages for a given time-frame, but if the delivery constantly fails, it will mark it as "old", "rejected" or similar, and it will store your recipient email address in our bounce list. To prevent email bouncing related issues please read :
In addition, you can find our mail server domain list from this guide: https://www.jotform.com/help/145-Whitelisting-JotMails-IP-Addresses. You may consider adding the list on your whitelist settings.
If the issue continues, our best recommendation to avoid email bouncing issues is to use your own SMTP settings for the sender email: https://www.jotform.com/help/244-How-to-Setup-SMTP-for-a-Form
