Can I set the default author of mail created tickets to a dummy customer in Jira SD?

Hello,

we got the problem that every communication in a specific project needs to be via mail between a customer and agent.

We already have JETI and ScriptRunner installed so we can extract the private email of the customer in a ticket (created by xyz@mail.com) into a custom field and use this in JETI. When the ticket is created by xyz@mail.com and the agent comments on this ticket an automated mail gets send to xyz@mail.com with the agent comment. The customer then replys to the agent comment which is then attached to the original ticket and the agent can go on with working.

Now our problem - in JETI we have the option to send the agent comment via email when agent comment event or customer comment event fires (we chose agent of course). But when the customer sends his mail back to respond to the agent comment, his or her comment will internally be placed by an agent dummy user -> which fires the agent comment event and he then gets his own commentmail send back to his mail adress.

So is it allowed to set this dummy for mail creation tickets or comments sent via email as a dummy customer account in this project and give this customer acc the rights of an agent (create ticket, comment ticket, update ticket...) or is there another workaround?
