Easy to maintain MS Exchange Alternative
Spam - This isn't that bad as long as you are actually actively adding spam to the spam db. I generally tell people to use Postcreen to cut down on spam bots and use postwhite to whitelist common legitimate email senders.

Domains and Email hosting
You can self host email if you really want to, but it's really more trouble than it's worth. If you do self host, you have to worry about the consequences of missed emails if your server or Internet ever goes down, and you'll have to use someone else's SMTP server if you don't want your emails to go directly to spam. The cheapest good SMTP server is Amazon SES, which I believe is $0.10 per 10k emails. I've been looking into mailcow for self hosting an email server and it seems the best way to go.

Ok, I've migrated email to selfhosted
However, https://mailcow.email/ is the ONLY exclusion I make for that. As it's an all in one docker managed solution. Where the only things you have to worry about is the reputation of your mailing IP.

Any self hosted disposable email address generators?
But its probably easier to use a dockerized container with all the mail stuff integrated and pre-setup like: https://mailcow.email/
