hi friend, I have a postfix server install on my work, and I have too configured a sasl auth mechanismus, my question is, how can I say to postfix tha use only the SMTP auth mechanismus.
Why i ask this question. Because if i use a mail client without any autentication machanismus to send mails the server sends the mails, and I need that the only way to send mails be the SMTP auth.
