This article provides a troubleshooting plan to ensure that the Caspio notification emails will be accepted by your internal email server.

Follow the steps below to verify your notification emails work properly.

  1. Open your DataPage in edit mode and proceed to the screen where the notification email is configured.
  2. For troubleshooting purposes, add another email address to the To field. Use a Yahoo or Gmail email address and see if the email is received. If yes, proceed to the next step. If not, contact Caspio Support.
  3. If the notification email to Yahoo or Gmail address is successfully received but the email to your domain failed, your mail server security settings are most likely blocking emails from Caspio.

This article includes IP addresses which Caspio utilizes to send automatic emails. Pass the following information to your email server administrator to whitelist Caspio mailers (caspiomail.com) by adding them in their SPF and TXT records. We recommend that the entire caspiomail.com domain is included rather than individuals IPs (example: v=”spf1 mx:caspiomail.com ~all”). This way, further updates will not be necessary when Caspio needs to change/expand IPs in the future.

While we cannot restrict our operations department to use only a few IP addresses, we can provide you with the current MX records that we are using. They can also be found by running a report against the “caspio.com” and “caspiomail.com” domains for MX records. For example, running “nslookup -type=mx caspio.com” from a command prompt window, will provide the following information on a Windows system.

MX records for ‘caspio.com’:

Preference Host Name IP Address
10 elta.caspio.com 52.52.212.89
20 mailer1.caspiomail.com 54.235.168.232

Similarly, running “nslookup -type=mx caspiomail.com” from a command prompt window, will provide the following information on a Windows system.

MX records for ‘caspiomail.com’:

Preference Host Name IP Address
10 mailer-us-01.caspiomail.com 34.195.1.189
20 mailer-us-02.caspiomail.com 34.233.178.65
25 mailer-us-03.caspiomail.com 34.228.127.162 **New**
30 mailer-au-01.caspiomail.com 13.211.118.229
40 mailer-eu-01.caspiomail.com 34.240.132.226
50 mailer-sa-01.caspiomail.com 18.231.38.135

Note: We reserve the right to change those records without any prior notice, but it is only done in cases of absolute necessity. In case of future IP changes, your email server administrator can easily check the MX records and update their rules.
