   1. Install Postfix from Ports

       $ cd /usr/ports/mail/postfix
      $ make install clean

      • When prompted to activate postfix in /etc/mail/mailer.conf, enter "y".

      Would you like to activate Postfix in /etc/mail/mailer.conf [n]? y

   2. Configure Postfix

      $ cd /usr/local/etc/postfix
      $ vim main.cf:
      	uncomment "myorigin = $mydomain"
      	uncomment "mydestination = $myhostname, localhost.$mydomain, localhost"
      	uncomment "mynetworks_style = host"
      	uncomment "alias_maps = hash:/etc/aliases"
      	uncomment "alias_database = hash:/etc/aliases"
      $ postfix start

      • Check /var/log/maillog
2. Setup SMTP AUTH to ipHouse
   • To keep mail from being routed over private frames downtown.
   1. Add the following lines to main.cf:

      relayhost = smtp.iphouse.com
       smtp_sasl_auth_enable = yes
       smtp_sasl_password_maps = hash:/usr/local/etc/postfix/saslpw
       smtp_sasl_security_options =

   2. Create password file and map for authentication:

      $ echo "smtp.iphouse.com        nobody@claimlynx.com:itaot" > saslpw
      $ postmap saslpw
