Yep, that's why I specified "end user" and "set aside internal company e-mails".

I never thought about the idea of having a "family domain", it could be a nice idea, though I guess its naming could be a possible venue for in-family disputes?

Rather than having in-family disputes, I've had relatively poor luck giving way vanity email addresses to family members. There's a lack of understanding and interest in how the email address would work in combination with an existing email account.

My name is "Mark Stosberg" and my email is "[email protected]".

Yep, I meant that:

1) my mom won't have an e-mail address with the surname of her first husband (my dad, passed away)

2) my brother-in-law (brother of my wife) surely won't have it

3) my cousins all have different surnames

4) my wife may accept one, but I talk with her every day and when we don't meet or talk via phone we tend to communicate via post-its on the fridge or similar
