Part 01: Ubuntu: install and configure SMTP server with Exim

Step 1: edit file /etc/exim4/conf.d/main/03_exim4-config_tlsoptions

add line: MAIN_TLS_ENABLE = yes
AUTH_SERVER_ALLOW_NOTLS_PASSWORDS = yes
AUTH_CLIENT_ALLOW_NOTLS_PASSWORDS = yes

Step 2: create user

sudo /usr/share/doc/exim4-base/examples/exim-adduser

data will store in file /etc/exim4/passwd

Step 3:
sudo chown root:Debian-exim /etc/exim4/passwd
sudo chmod 640 /etc/exim4/passwd

Step 4: edit file /etc/exim4/conf.d/auth/30_exim4-config_examples

Comment all line, only uncomment these lines:

 plain_server:
   driver = plaintext
   public_name = PLAIN
   server_condition = "${if crypteq{$auth3}{${extract{1}{:}{${lookup{$auth2}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}{1}{0}}"
   server_set_id = $auth2
   server_prompts = :
   .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS
   server_advertise_condition = ${if eq{$tls_in_cipher}{}{}{*}}
   .endif
 login_server:
   driver = plaintext
   public_name = LOGIN
   server_prompts = "Username:: : Password::"
   server_condition = "${if crypteq{$auth2}{${extract{1}{:}{${lookup{$auth1}lsearch{CONFDIR/passwd}{$value}{*:*}}}}}{1}{0}}"
   server_set_id = $auth1
   .ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS
   server_advertise_condition = ${if eq{$tls_in_cipher}{}{}{*}}
   .endif
