      1. Go to Client communication -> E-mail settings
      2. Set options Contact e-mail address: and Return e-mail address:
      3. Set Use SMTP server for e-mail to No
      4. Send any email via FreeBSD and its sendmail.
      5. You will have such headers in your email (example):

      Return-Path: <www@www.phpbb.com>
      Received: from www.phpbb.com (localhost.phpbb.com [])
              by www.phpbb.com (8.14.4/8.14.4) with ESMTP id p1393qkQ058973

      As you can see there is no original phpBB's Return-Path line.

      I speak about line from file /includes/functions_messenger.php

      $headers[] = 'Reply-To: ' . $this->replyto;
      $headers[] = 'Return-Path: <' . $config['board_email'] . '>';
      $headers[] = 'Sender: <' . $config['board_email'] . '>';

      This happens as I see because you don't use -f <> option for sendmail as many others coders and scripts uses.

      For example from vBulletin software:

      if (!SAFEMODE AND $this->registry->options['needfromemail'])
      $result =  @mail($this->toemail, $this->subject, $this->message, trim($this->headers), '-f ' . $this->fromemail);
      $result = @mail($this->toemail, $this->subject, $this->message, trim($this->headers));

      In FreeBSD mail config files /etc/mail there is such string:

      H?P?Return-Path: <$g>

      The explanation for this line:

      This line defines a field called Return-Path: that displays the contents of the $g macro (sender address relative to the receiver). The ?P? portion indicates that this line is only used if the mailer uses the P flag (the mailer requires a Return-Path line).

      So if no -f <> option is used for sendmail and there will be any Return-Path: string in mail headers
      then it will be replaces with sendmails own Return-Path: string via code:

      H?P?Return-Path: <$g>
