Creating Issues along with Image Signature by Apple Mail, Gmail and etc, Creates Attachments

Summary

Creating Issues along with Image Signature by Apple Mail or any other Email service which includes the attachment in body of mail and not footer(Gmail can be configured properly in footer), Creates Attachments

Environment

Using Apple Mail to create issue in JIRA Service Desk

Steps to Reproduce

When user is using Apple Mail to send an email to JIRA SD in order to create issues, if there is any signature on that email regardless of the image being inside the body of email or in the footer of the email. JIRA creates attachments
Image signatures of the emails by Apple Mail appear as attachment in the ticket. So, multiple replies may create many attachments which need to be removed manually and it triggers the issue update event which results in receiving unwanted notification to users.

Below is the part of the original message from Apple Mail, which shows that the image signature will be sent as part of content of the mail, not footer.

--Apple-Mail=_4A78E496-79D6-4AEB-BB9D-EBAA25EF99D9
Content-Transfer-Encoding: base64
Content-Disposition: inline;
	filename="AF04260C-C4F8-4357-9410-25719D1D08C8[18].png"
Content-Type: image/png;
	name="AF04260C-C4F8-4357-9410-25719D1D08C8[18].png"
Content-Id: <79034FE9-D9CF-4811-93FC-C499B27C81DC@rhodon.com>

and below is the part of the mail which has been sent using Gmail and it can be seen that the image is in footer and will be ignored by JIRA and does not create any attachments

--001a1134b9644e9875050fdeae4d
Content-Type: text/plain; charset=UTF-8

This has an image as the footer.

*USERNAME*
*Support Engineer*
LOCATION AND PHONE NUMBER

--001a1134b9644e9875050fdeae4d
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

Expected Results

The expect result is any image other than those in footer to be added as an attachment, but it does not happen by Apple mail
