Blacklists are unidirectional. They are used by receiving mail servers to determine if the mail server sending the mail is a well known source of spam or maliciousness. They do not prevent a mail server that is on a blacklist from receiving mail, though that mail server itself may check the sender against blacklists.

If you inherited the mail server's IP from someone you can look it up on public blacklists to see if it's been marked, although public blacklists are sometimes hard to get removed from. Private blacklists cannot be searched but will sometimes autoreply to the sender or domain postmaster notifying them...

Private blacklists cannot be searched but will sometimes autoreply to the sender or domain postmaster notifying them of a refused delivery along with a contact email for removal. Microsoft maintains a fairly extensive private blacklist for their hosted exchange service. I've had to get several of my subnets off of it.
