Ah yes, the classic "your IP is on a mysterious blocklist" struggle. Nothing like setting up a mail server only to find out the internet thinks you're a spammer. Postfix relay on a VPS is a solid move—more control, fewer headaches. If you're ever looking for budget dedicated servers to handle your mail server or anything else, HostNoc has some solid options. Good luck keeping the emails flowing!
