Example:
My account *Hagerty use command: /Mail hagerty Test --> Could not sent.
My another account *Menu use command /Mail menu Test --> Email sent
when *Hagerty use command /Mail menu test --> Could not sent email again
So you cant check is other account email registered if your own account is not email registered
True Story?
it's because theres some auto-set option in diablo that blocks mail from accounts (or accounts not on your friends list)
i never took the time to explore the settings and test stuff with it, thats why i say test from the account you're checking, that way it isn't able to give a false positive like you see

i don't think it matters if your acct is email reg'd or not, im pretty sure it had something to do with a 'block incoming mail' or 'block unknown users' or something along those lines, sort of setting somewhere that i havent found
