Summary
Body Regexes allow you to remove content from the email that should not be added to the Issue Description or Comment. For example Signatures or Forwarded email prefix.
Body Delimiter expressions are always prefixed with a leading \n to reduce false positives. For performance reasons .* isn't allowed - use more specific patterns instead.
Pre Field Processor Body Clean-up
This features allows you to remove specific lines of content before the Field Processor has processed the email. This allows you to remove content that may interfere with the detection of directives.
In this example we are using the Pre Field Processor Body Clean-up Regex to strip out unwanted header data from an email we are forwarding. Here is what our incoming email looks like:

Create/Comment Post Field Processor Body Clean-up - Applies to both Create and Comment
This features allows you to remove specific lines of content after the Field Processor has processed the email. This allows you to remove content that may interfere with the detection of directives. This option can be configured to be used when Creating or Commenting on a issue.

Change when the Body Delimiter/Post Field Processor Body Clean-up is applied
The Body Delimiter can be configured to be applied either on Create or Comment. You must add the Body Delimiter to both Create and Comment if you require this to apply to both Create and Comment.
Specifying Create Only Body Delimiters/Clean-up
Press Create when you are in the Pre-Processing configuration. This will then change the Body Processor section to show the Delimiters that only apply during creation.
Specifying Comment Only Body Delimiters/Clean-up
Press Comment within the Pre-Processing configuration. This will then change the Body Processor section to show the Delimiters that only apply when commenting on a Issue.
Enabling and Disabling JEMHC Predefined Body Delimiters
Within the profile there are some predefined Body Delimiters which are created to match on common information that you may not want in the description/comment e.g. previous replies. These can be enabled or disabled by selecting the relevant Regex within Create/Comment Body Delimiter Regexes.
Enabling Predefined Body Delimiters
Go to Body Processor section and press Edit
Select either Create or Comment (Depending on when you want to the Delimiter to apply). Create in this example.
Select the Predefined Body Delimiter (e.g.
--?\n) and press save.Once saved you will be able to see that the Body Delimiter has been Enabled within the Summary of the Pre-Processing section.
Disabling Predefined Body Delimiters
Go to Body Processor section and press Edit
Select either Create or Comment (Depending on when you do not want the Delimiter to apply). Create in this example.
Hold down the CTRL key and Select (Left Mouse button) the Predefined Body Delimiter (e.g.
--?\n) and press save.Once saved, you will see that the Body Delimiter can only be seen within the Pre-Processing summary.
