Modern email systems don't seem to use Greylisting. I used it many years go but it seems to have gone out of fashion nowdays. I now use Fastmail which doesn't seem to employ Greylisting (or at least I've never seen it become an issue). I suppose spammers have now gotten wise to it and have now devised ways to get round it so it's no longer effective and thus no longer widely used.
- viraptor 6y agoI'm running my email on a private, small volume domain. Greylisting is still super popular and common. You won't experience greylisting on popular domains... because they're popular.
- fullstop 6y agoI set up greylisting on our MTA and eventually had to remove it. While I was okay with waiting a while to receive a message other people were incredibly frustrated with it. It was particularly troublesome when a service would send them a code in email, it didn't arrive, and then they would ask for another one. The first code would finally arrive, but it was marked as invalid because the second code that they had asked for was now the valid one. It just wasn't worth the trouble and headaches.
