Removing subject content from incoming emails
Summary
The Pre Field Processor Subject Clean-up Regexp feature will remove any matching content from the Subject of the email. This feature allows you to remove sensitive data that may have been sent within the Subject of the email. e.g. an employee Id number.
For performance reasons .* isn't allowed - use more specific patterns instead.
Adding a Subject Regex
To remove content from the Subject you must add a Regex to Pre Field Processor Subject Clean-up Regexes which can be found within JEMHC > Profile > Project Mapping > Pre-Processing
Now you will be able to add the relevant Regex that will remove content from the subject.
Removing Forward Prefix
Typically when emails are forwarded they will contain a Subject Prefix (e.g. Fw:, Fwd:). By default the Prefixes checked here are guided for English format emails that use Fw and Fwd. Forwarded Email Subject Prefixes can be adapted to include more prefixes so that they can be matched by JEMHCloud.
When the Prefix has been matched by JEMHCloud it will result in the Prefix being removed and any Post Field Processor Body Delimiter/Clean-up from being applied.
Pre Field Processors Body Clean-up/Delimiter will still be applied.
Example
