we have an issue with "Configuring Custom Email Senders". When we firs

So as I understand I need to define a constant where I will save an user from which e-mail adress i wil sent those system mails.Than I will need to redefine the conf. file like this:
<?xml version="1.0" encoding="UTF-8" ?>
- <emailConfig>
- <addresses>
- <address name="process">
- <!-- This name is a key which needs to be specified in the collection to which it belongs
-->
<expression>=getProcessEmail(pp!id)</expression>
- <!-- Either emailAddress or expression
-->
</address>
- <address name="processModel">
<expression>=getProcessModelEmail(pm!id)</expression>
</address>
- <address name="processInitiator">
<expression>=toemailaddress(user(pp!initiator,"email"))</expression>
</address>
- <address name="processDesigner">
<expression>=toemailaddress(user(pp!designer,"email"))</expression>
</address>
address name="Appian BPMS">
<expression>=toemailaddress(user(cons!CUSTOM_USER, "email"))</expression>
</address>
</addresses>
- <collections>
- <collection name="from">
- <items>
<item>AppianBPMS</item>
<item>process</item>
<item>processModel</item>
<item>processInitiator</item>
<item>processDesigner</item>
</items>
</collection>
And after restarting server,we need to do save and publish on each process model where we use Sent Mail smart service.
Right or it will be implemented automatically?
The links that you are sharing with me are for Appian 7.5 but there compatible with Appian 7.0?
What about when we do next modification on any application and export import it on PROD is there anything that we need to do?
