Duplicate attachments created from images inserted to HTML e-mails when comments added from follow-up messages

Problem Definition

Each time users that send emails to a designated mailbox from which Jira retrieves them in order to create new tickets or add comments to existing ones usually contain footers with company's logos, marketing imagery or some standard text. All these attachments are autiomatically added to tickets into file attachments therefore cluttering important content.

Assume the following scenario:
1. New issue created from an e-mail message (HTML) and image attachment added to the issue
2. above issue.is commented from the reply e-mail
Result: the images from original part of message are attached once again.

With long correspondence the amount of duplicated images becomes VERY big.

Suggested Solution

Could we have an option to create filters or a new option in Jira's ticket that allows to remove existing and ignore future content or attachments files in newly retrieved messages? Ideally in files attachments one would click option and select "Remove and ignore" or have a dedicated feature to manageme ignored files and text content that is being removed for each email message going into JIRA. This could be global, per project or even per ticket etc.
