I have a website that has a subscribe section. When a user subscribes the website sends an email to me. Just recently it's been sending me blank emails. It now only works if I configure my sender email to be different to the email it sends to.
Eg I configured my site to send details of the subscriber from info@domain.com to my info@domain.com email when someone subscribes to my site. That has stopped working.
But works if I change the sender or receiver email eg. test@domain.com to send to info@domain.com (so it's not working if the email is set to send to itself)
But I want for it to send from info@domain.com to info@domain.com
Any ideas how I could make this work? as mentioned it was working and suddenly stopped on 30 November.
