We have to use de function sender_dependent_default_transport_maps.

  • Edit a new file
 vi sdd_transport_maps.regexp

 /@opilab\.ch$/      opilab_ch:
 /@opilab\.com$/     opilab.com:
  • Edit master.conf
 vi /etc/postfix/master.conf

 opilab_ch   unix -       -       n       -       -       smtp
       -o smtp_bind_address=IP1
       -o smtp_helo_name=opilab.ch
       -o syslog_name=postfix-opilab_ch
 opilab_com   unix -       -       n       -       -       smtp
       -o smtp_bind_address=IP2
       -o smtp_helo_name=opilab.com
       -o syslog_name=postfix-opilab_com
