Curious why this matters? Let's say you know abc@foo.com is hosted on gmail, so what?
- nzach 2y agoIn this case is safe to assume abc@foo.com, a.b.c@foo.com and abc+def@foo.com are all the same inbox. So you can just use the canonical form (abc@foo.com) to hide where you got this email address from.
