Mail forwarding does not work on Postifx server.


Incorrect configured file /usr/sbin/sendmail.postfix or it is configured as a link to some file.


  1. Check sendmail file as below:

    # grep ^sendmail_path /etc/postfix/
    sendmail_path = /usr/sbin/sendmail.postfix
  2. Make sure that it is physical file (not a link):

    # ll /usr/sbin/sendmail.postfix
    -rwxr-x--- 1 root postdrop 267232 Apr 25  2014 /usr/sbin/sendmail.postfix

On test installation Plesk 12.0.8 with Centos 6:

    # ll /usr/sbin/sendmail.postfix
    -rwxr-x--- 1 root postdrop 267232 Apr 25  2014 /usr/sbin/sendmail.postfix

    # md5sum /usr/sbin/sendmail.postfix
    c6841434dfbbd1b946a39a1ab8918666  /usr/sbin/sendmail.postfix

If it is not a physical file, replace file from postfix-2.8.17-14042513.x86_64.rpm package (or from distributive of current installed Postifix version):

  1. Download postfix-2.8.17-14042513.x86_64.rpm from

    # mkdir postfixtest
    # cd postfixtest
    # wget
  2. Unpack package:

    # rpm2cpio postfix-2.8.17-14042513.x86_64.rpm | cpio -idmv
  3. Replace /usr/sbin/sendmail.postfix:

    # pwd
    # mv usr/sbin/sendmail.postfix /usr/sbin/
    mv: overwrite `/usr/sbin/sendmail.postfix'? y
    # chown root:postdrop /usr/sbin/sendmail.postfix
    # chmod 0750 /usr/sbin/sendmail.postfix
