Adding a comment to a task in response to a notification via email

[Helen Porter]

Hi

We need to add a comment to the email task in response to the notification from JIRA.
For example, a user receives a notification about a comment from a task, but without logging in to JIRA, he wrote a response via "Reply" in the mail, and this response was added as a comment to the task.
Can I configure the response so that only a comment is added to the task, without part of the notification that the user responds to?
We have configured the mail handler so that the notification text is not included in the comment. Used: Split Regex. But from the notification, along with the comment, an image (an icon of the task type) is attached to the task. How do I exclude adding this icon?
