I’ve using Mozilla Relay to generate one new email address for every website that I have to register. Lately it seems tho that the big/medium sites are rejecting any email from mozmail.com, some even say “temporary email services are not allowed”.
Is this just with the service from Mozilla or is it becoming general practice? Is there any service that is still flying under the radar?
I used it on github and that got my account flagged. I had to change it to an email registered to my domain to get my account back to normal. I think there was one other site I had issues with in my years with the service but I can’t remember which site it was.
