I have a postfix/dovecot setup for a personal mail account. It's really just a one-man mail setup.
Now I want to move my setup to a new VPS which means it'd get a new IPv4 address. My concern is that I'm getting blacklisted because I use a new address. Is that a legit concern or am I just fine using whatever IP address as long as my (r)DNS records are fine?
To answer anx' question: Why the one-man setup?
