Hi, Look at Lena's block cracking. There is a section of what you need, i think.

Actually, my configure file look like as: ... acl_smtp_auth = smtp_auth acl_smtp_rcpt = check_rcpt acl_smtp_data = check_spam ... begin acl smtp_auth: accept check_rcpt: accept authenticated = fixed_login accept condition = ${perl{check_deliver}{$domain}{$local_part}} accept condition = ${perl{checkvalias}{$domain}{$local_part}} deny message = User unknown check_spam: warn condition = ${if <{$message_size}{SPAM_CHK_MAXSIZE}{1}{0}} message = X-Spam-Score-Int: $spam_score_int spam = nobody:true/defer_ok deny condition = ${if >{$spam_score_int}{SPAM_SCOREINT_TO_DISCARD}{1}{0}} message = Our mail system has determined your message to be SPAM. spam = nobody:true accept begin authenticators fixed_login: driver = plaintext public_name = LOGIN server_prompts = "Username:: : Password::" server_condition = "${perl{checkuserpass}{$auth1}{$auth2}}" server_set_id = $auth1 I thinks that where I made the check to authenticated at check_rcpt it's wrong. It's this really wrong? If it's wrong, where I may does the control? At smtp_auth (acl_smtp_auth) section? It may be this way? smtp_auth: drop !authenticated = fixed_login accept check_rcpt: accept condition = ${perl{check_deliver}{$domain}{$local_part}} accept condition = ${perl{checkvalias}{$domain}{$local_part}} deny message = User unknown An if this approach is correct, when drop at smtp_auth section, Exim immediately exit? or it does the remaining controls? Can anyone help me? Thanks in advance.
