myhostname = mail.tanjila.com

alias_maps = hash:/etc/postfix/aliases
alias_database = hash:/etc/postfix/aliases

transport_maps = hash:/etc/postfix/transport

myorigin = tanjila.com

mydestination = tanjila.com, mail.tanjila.com, localhost.tanjila.com, localhost, hash:/etc/postfix/transport

mynetworks = 127.0.0.0/8, 122.144.9.74/32 [::ffff:127.0.0.0]/104 [::1]/128

Postfix SASL authentication with SMTP port 465:

  By default postfix SMTP works on 25 port.   You can check this by following command with the output below: #netstat -nat tcp        0      0 0.0.0.0:25             0.0.0.0:*               LISTEN    Here we will change the port to 465 with SASL authentication. It is useful technique to fight against spam. Users those travel here and there with their laptops need not to change their e-mail client software settings also. Here is how we can do it.   Step 1 . Edit the file /etc/dovecot.conf and make sure your auth default section has the lines below. auth default { socket listen {   client {    path = /var/spool/postfix/private/auth    mode = 0660    user = postfix    group = postfix     }   }   mechanisms = plain login } Step 2 . Edit /etc/postfix/main.cf , find the keys below and change its values as follows or add it at the bottom of the file if the key (the word before the = sign) cannot be found. mynetworks = 127.0.0.0/8 smtpd_sasl_type
