Age may be a factor. I ran email for my domain on my own server for a long time too and generally had no delivery issues.
When I got another domain a few years ago and ran it on the same server it had a lot of delivery issues.
Probably. Although I switched both IP and domain a couple of years ago (not at the same time) without noticeable issues.
