@kybean@ryanc '""@[ffx3::]@10.0.2.010' is a fun one. At the end of the day, basically the only way to determine if an e-mail address is valid is to check to see if there's at least one @ in there and attempt to send it.
@j@kybean Yeah, I use example@example.com for WiFi captive portals because they basically never validate it and screw their request for my info.
Meanwhile, the free WiFi at the Bangalore airport wants either a passport (which gives you a code for one device) or an Indian mobile number, and it infuriates me.
