Why? If my webserver goes down, I can move the hoster, reboot the server or otherwise fix the problem.

If my webserver or worse, my domain, ends up on a spam blacklist, either due to moronic/malicious users flagging my mails as spam or due to automatic triggering running amok, then I have no way of ever getting my sign-in working again except of praying that the blacklist manager(s) will unblock me. Which rarely happens.

The webserver being in a blacklist can be solved by signing up to some SMTP relay. The domain blacklist can be solved by just buying another.

This is the perspective of the service provider. From the user POV, if their domain gets blacklisted, they can still receive emails, and therefore can still login as usual.
