Introduction
As an administrator it may be desirable to exclude certain attachment files based on their file size or name/content type. A common use case for attachment exclusion is images contained within email signatures. Signature images are often icon sized so as an administrator you could exclude all image files below a certain file size to filter these attachments from created issues. Attachment exclusion can be configured globally or at project level by a project administrator.

Attachment Content Types | A list of MIME content types to be excluded. A super type can also be chosen such as "image" to block all image/ content types. |
File Size Range (bytes) | A file size range (in bytes) of files to be excluded, can be used in combination with other configuration options within the rule. |
File Names | A comma separated list of regular expressions used to match against file names destined to be excluded. |
Reason | An optional reason that can be defined for the exclusion rule for future reference. |
Project Key | The project that the rule will be scoped to, by default rules are scoped globally meaning they apply to all projects. Selecting a specific project will scope the rule to that project only. |
