"Send email from comment" automation is creating new issues in the project

[Luis David Montes de Oca Hurtado]

Hello team, 

I have a mail handler "luis@support.me" to create a jira ticket in a specific project (JSM) and all the reply's as a comment (Using the Issue Key) Also I'm creating an automation to send the reply's to email for non jira users from the comments of the jira project.

However since I'm using the same mail handler in the automation, It's creating a comment and a new issue to the project with the comment from us as a description. 

Brainstorming: 

I was reading this documentation to see if there's an option to catch only the "to" field in the email, unfortannely is only the address. 

I created a custom field to get the sender's email and make the automation based on that, however is not going to be in the email thread 

Question: 

What's the best option to do it and avoid the new issues creation since is going to affect the data of the project?

Hope you can help me with that and thanks in advance!

Here's the automation I have so far: 

 

I have the comparison statement, because we add internal comments and we shouldn't send an email reply with those.
