> I'd love to tell people the only way to replace gmail is to get either your own mail server or at least your own domain, It's trivially easy to get blacklisted as spam that way...
This is kind of FUD. I’ve been running my own mail server for over a year now, and my E-mails don’t magically disappear into some blacklist. Do you have to be careful when configuring your server? Yes. Can you get on a blacklist erroneously? Yes. Does not going with a hosted solution mean you cannot participate in E-mail? No way. I don’t know where this myth comes from that running your own mail infra means your mail…
Aside from Yahoo though, we generally haven't experienced any blacklisting or deliverability issues. It does require time to setup properly and maintain however, you can't just set it up and forget about it.
