So we’re getting a lot of Undelivered Mail Returned to Sender for @hotmail, @outlook etc mailboxes. I believe the DO IP based in London is listed as blocked with MS.
Question 1) Does anyone know a data centre with IP range that isn’t blocked by MS?
Question 2) Yesterday I tried Amsterdam 3 (recommended by someone on this forum). I took a snapshot of my LON droplet with MIAB and turned it off. I then created a new droplet from that snapshot but in Amsterdam 3 and then updated my glue records to match the new IP. I then ran sudo mailinabox and nothing seemed to be right. I even tried a reboot. I continually got ‘nsd4 is not running’ and nothing seemed to be right. I have reverted back to the old LON droplet but what did I do wrong?
Any help would be much appreciated.
