Hello,
I have a question about sendmail and mail in
general.
I want to know is it possible to know if there are some specific users in some specific
servers.
for example On mydomain.com I have user myuser@xxxxxxxxxxxx, and people from
outside want to know if this user exists or not ?, so how can they do that
?. I mean to know this, without sending email. Otherwise they can send
email, and if the mail does not come back, It means the user
exists :).
Or without sending email to him, how can I know, is
there a such user ivantan@xxxxxxxxxxx ?.
Thanks in advance.
Rudolf.
