Re: [mailop] warming up IPs, Microsoft?

Huh. We don't have any issues sending email to them from Linode, including a small number from one of our new IP addresses I've been trying to warm up. Linode has a bunch of different IP address blocks and I would expect recipients to block the ones that send annoying amounts of spam. That's

Re: [mailop] warming up IPs, Microsoft?

It also occurs to me that you don't need to do your computing and mail on the same VM. Mail is rather lightweight so you could run a mail server at Tektonic, and send messages from other places via port 587 submission. On Sun, 5 Mar 2023, Mark Fletcher wrote: On Sun, Mar 5, 2023 at 10:20 AM
