  For those that run across this, here is a solution to setting the outgoing IP Address for Qmail on a Plesk server that does not support the /var/qmail/control/outgoingip file.

  Use iptables instead !

  https://www.nixtree.com/blog/change-outgoing-ip-address-for-smtp-using-iptables/

  iptables -t nat -A POSTROUTING -p tcp --dport 25 -j SNAT --to-source xx.xx.xx.xx

  You will probably need to change the script /etc/rc.d/init.d/psa-firewall to add this in the "start" section because when Plesk restarts the firewall it will bump the rule out you added manually.
