Im very new to Jira, thank you for your help!

Hello @Goldmann

Welcome to the Atlassian Community!

You can configure an e-mail handler to configure the option to create issues through e-mail and adds comments to existing issues. These would be the steps:

1. Choose  > System
2. Select Mail > Incoming Mail. 
3. Click Add incoming mail handler (or click Edit next to an existing mail handler).
4. Enter a name that describes what your mail handler will do (e.g. "Create issues or comments from Company A's IMAP mail server")

5. Select the default server, or choose a server if additional ones have been configured.  

6. Specify the delay in minutes between the mail handler's running time, or the frequency with which the mail server is scanned.
7. Choose the type of mail handler (more info on the default mail handlers below).
8. Click Next to fill in options specific to the selected mail handler. 

9. Click Test to make sure your mail handler is working properly.

Once you configure the handler, you just need to send an e-mail to the Jira incoming e-mail address adding the summary of the e-mail with the key of the issue you want to comment on. Basically, any replies sent to the issue created notification will add a new comment to the issue:

To: jira@example.com
From: some-jira-user@example.com
Subject: (TEST-123) issue key 
Body of the email is the comment that will be added
