Wrong addresses = mailing problems.

[Rodolfo Gonzalez Gonzalez <rgg @ labpar1 . cs . buap . mx>]

Hi,

I had a problem few minutes ago. I tried to send mail to one of my
mailing lists and the mailer returned complaining about an unavailable
service, because of a wrong address. Someone had subscribed with an
address like @prime.net (that's, without a name), and apparently Majordomo
didn't catch it, and it was causing errors. Two questions: 

1.- why did not Majordomo catch this address (@prime.net)? 
2.- what can I do to avoid this kind of subscriptions?.

Thanks in advance.
