Hello!

The solution to my problem might or might not be related
to the vchkpw, so i'll try to find help here anyway.

The problem is that if there is a virtual domain: bbb.zz
and there is a user [EMAIL PROTECTED]  and the whole thing
is located at address ADDR then any spammer 
can connect to smtp port on addres ADDR enter
[EMAIL PROTECTED] as FROM address (MAIL FROM) and
spam a bunch of people. All the victims will think
that [EMAIL PROTECTED] is doing it to them.  Relaying is
allowed in this case, since bbb.zz is a local domain.

How can I solve the problem? SMTP authorization?
but how? Any other ways?

Regards,
Artem
