Configuring SASL
Postfix supports two SASL implementations: Cyrus SASL and Dovecot SASL. To enable Dovecot SASL the dovecot-core package will need to be installed: sudo apt i n s t a l l dovecot−c o r e Next, edit /etc/dovecot/conf.d/10−master.conf and change the following: s e r v i c e auth { # auth_socket_path p o i n t s t o t h i s us e rdb s o c k e t by d e f a u l t . I t ’ s t y p i c a l l y # used by dovecot−lda , doveadm , p o s s i b l y imap p r o c e s s , e t c .

Now it is time to test the setup. To see if SMTP-AUTH and TLS work properly, run the following command: t e l n e t m a i l . example . com 25 After you have established the connection to the Postfix mail server, type: e h l o m a i l . example . com 254 If you see the following in the output, then everything is working perfectly. Type quit to exit. 250−STARTTLS 250−AUTH LOGIN PLAIN 250−AUTH=LOGIN PLAIN 250 8BITMIME Download 1.27 Mb. Do'stlaringiz bilan baham: |
