For more info see:

Comment count rate limit filter

Checks the number of incoming messages for the certain period of time. This is a denial of service attack preventative and anti-email-loop measure

Non-delivery filter

Intercepts non-delivery messages from mail servers and drops (failure in processing will result in a forward). This filter checks all message parts to see if they have a Content type of “multipart/report” with a Report type of “delivery-status”. This includes attachments as some Mail Server will contain the Non-Delivery report as an attachment so this ensures they cannot create new issues.

Directive Set Reply filter

When an incoming email contains a Directive Set token within the Subject. The Subject would need to contain “JEMH_TOKEN=dc2344…” in order to match.

For more info see:

Non JIRA account holder Security Check filter

A security filter that can reject emails from non-jira users, that refer to an existing issue where that sender is not already involved (added as a non-jira user to a TEXT custom field)

Comment count limit filter

Checks incoming messages for specific limits, regarding size, and comment count on an issue. This is a denial of service attack preventative and anti-email-loop measure.

Exchange Auto Response filter

Filters emails which contain both the X-Auto-Response-Suppress and X-MS-Exchange-Inbox-Rules-Loop headers
