Indeed, this is a great advantage of running my own mail server. Since I'm only providing mail for me, my family and a couple of friends, I can do things that a real ISP couldn't even consider, like refuse mail from all non-whitelisted senders at major ISPs with non-functioning postmaster addresses (e.g. sbcglocal.net, rr.com), huge 419 problems (e.g. tiscali.co.uk) etc. I can only do this because the range of correspondents I need to be able to deal with is strictly limited and I can handle the whitelisting requirements. So, for instance, being in the UK I have to deal with lots of people at big UK ISPs with broken postmaster addresses (e.g. virgin.net), so I whitelist the ISP from the postmaster check, but for US ISPs, where the number of correspondents is much smaller, I can afford to individually whitelist addresses.
