Yikes, I use service@domain quite often. I didn't give thought to this possibility.

I'm quite sure the reason will be that this service emails others on "your behalf" and probably does something like placing your email address in the "From" field or in the body of correspondence. I assume they are concerned about phishing or catfishing emails purporting to be from the service.

This doesn't appear to be an adequate solution to the problem.

Something like $(hex(hmac(secret_key, service)))@domain could solve that. It would also mean service can't pretend to be another-service@domain when spamming you.

Though who knows, maybe hex addresses will look fake / malicious and trigger a ban anyway.

Zomato refused to change my email to zomato@ (you need to create a support ticket). However, they agreed on otamoz@ (strrev(zomato)).

It's an email, not a "secret", something like 3 or 4 hex (or even better, base58) digits should be more than enough
