We use an application which sends emails in the form of a text messages to T-Mobile users to below domains in the format MOBILENUMBER@DOMAIN (Example :

We are making changes in the way, emails are been sent from our company to mobile carriers and would like you to whitelist particular IPs at your end to continue with this mail-to-text functionality.

Thank you!
