It is a common problem that with intensive email conversations the same content from email attachments (e.g. email signature images) are added the same issue polluting the relevant content.
Email This Issue's Attachment Duplication Filter functionality prevents this by making sure that the same attachment content will be added only once from emails.
The duplication is based on MD5 Hashes calculated from the attachments' binary content.
If an Attachment Size Threshold is set in this page, then files being larger than the Threshold will not be filtered by duplication to avoid the overhead of calculating MD5 hashes for large files.

Duplication check is not applied to attachments uploaded explicitly via the Jira UI. |
MD5 Hashes - Filter by Content
MD5 fingerprints are used to exclude attachments from being added from emails. Email This Issue Mail Handler extracts attachmens from the incoming emails it processes and attaches them to the issue.
...
Files larger than the configured attachment size threshold will skip md5 generation and matching to minimize computation overhead.

In order to user MD5 filtering, a Email This Issue Mail Handler must be configured to process incoming emails. Please read docs and tutorials. |
Save Images from Email
Email clients like Outlook alter (e.g. resize) the images embedded in the email body. Therefore the most reliable way to apply the MD5 filtering is to follow the steps:
...
This way you can make sure that the image is filtered properly. Do not upload the original image because it will be a different stream of bytes resulting in different MD5 hash value.
Exclusions - Filter by Name
Attachments may filtered out by regular expressions matching the name of the files. Add name exclusiön patterns in the Attachment Filtering page. Attachments whose name matches either of the expressions added, will not be attached to the issues.
