how about [e-mail] and em@i.l

[jq-r]

I use [e-mail]. So even they send you some activation link you just go there and click it. Very convenient page.

[mongol]

example.com is officially on a list of example domains that will never be allocated to real use.

[Voklen]

I usually use e@e.e or if that fails [e-mail] or if even that fails [e-mail]
