I am just testing setting up my kumomta server and sent to a list of 4 emails (all my own, fastmail and gmail accounts) to see my kumomta msgs and understand how everything works… ive sent around 10 blasts to this 4 email list
My fastmail emails arrive, my gmail emails are bouncing with this msg:
The IP you’re using to send mail is not authorized to send email directly to our servers. Please use the SMTP relay at your service provider instead. For more information, go to 'The IP you're using to send email is not authorized...' - Gmail Help ffacd0b85a97d-4325e709c98si62714905f8f.75 - gsmtp
what did i do to get blocked? how should i interact with gmail with a brand new server? how am i supposed to warmup if they bounce me right away?
Have you googled “google blocked my new email sending ip”?
Google has specific instructions on registering your ip and domain for outbound sending. And as mentioned above, they also have e a blockist if known IP addresses that could be residential ISP or have know spam histories. You should check reputation and request it be removed from the block list.
