So, hosting email has two hard parts: - Spam filtering incoming mail. - Sending mail in a way that the other end will accept. The actual IMAP server part I'm happy to host myself, but these other two parts take up too much time. Right now I use gmail to do these two things, but it's imperfect for a lot of reasons. Would FastMail be a better choice for this? Or are there better ways to outsource these hard parts? I feel like there should be a reliable service that does just those bits, but I've never found one.
