Hi there!
I am getting a lot of messages blocked by Gmail with the following code:
So for what I can tell, they are fine with the IP of my SMTP server, but they don't like the sending domain.
Is it the sending domain the FROM?
Is it important to warm up both the sending domain and the IP of my SMPT server?
Thanks a lot!
