Sir,
I have one problem. I have an exim mail server. I have even configured
cyrus-sasl-pwcheck to do SMTP-AUTH.
It is checking /etc/passwd file to do the authentication. Now the problem is
even if the user who is trying to send a mail doesn't have a valid id in the
server, he can authenticate himself with someother users id and send mail in
his name.
For eg. if the user abc has an id like [EMAIL PROTECTED] in the server, another
users xyz who doesn't have a valid id, can authenticate himself with the user
id abc and send mail from id [EMAIL PROTECTED] i.e. user id used for user
authentication need not be same as sender's id. How to check whether user is
sending mail from authenticated id only.
I tried to get sender_address_local_part in AUTHENTICATION CONFIGURATION, but
could not. Please guide me how to proceed.
