Why you should not block slmail.me
SimpleLogin (by Proton) gives each website its own forwarding address. Mail sent to it reaches the person's real inbox, and they can reply. These users are privacy-conscious, often technical, and buy software at least as often as anyone else.
Many disposable-email lists wrongly include relays. Vetto keeps them out of the block list on purpose, tags them in your log, and still stops true throwaway services.

Frequently asked questions
Is slmail.me a disposable email address?
No. slmail.me belongs to SimpleLogin (by Proton): each address forwards to the person's real inbox. They read your emails, and many are exactly the privacy-minded customers who pay.
Should I block slmail.me?
No. Blocking relays turns away real customers. Vetto allows them and tags them as relays, so you can see them in your log without losing the signup.
Can someone use slmail.me to get several free trials?
In theory one person can create several relay addresses. That is rarer than Gmail aliasing and worth handling with per-account limits rather than by blocking the whole relay.
