Velocity Pre-Proc Task: Conditionally remove References and In-Reply-To headers
Summary
If you would like to conditionally stop Thread Matching by removing the References and In-Reply-To headers, then this can be done by using a Velocity Pre-Proc Script that will run the relevant condition (e.g. if subject contains a forward Prefix “Fwd:”) and if that condition is true then it will need to remove the References and In-Reply-To headers (if they exist). Once these headers are removed it will stop Thread Matching from occurring and will result in a new ticket being created.
Note: If a Issue Key is associated through other methods, e.g. a valid Issue Key within the subject or through a Directive, then a comment will still be added.
Example Script:
#if($message.getSubject().contains("Fwd:"))
#if($message.getHeader('References'))
$message.removeHeader('References')
#end
#if($message.getHeader('In-Reply-To'))
$message.removeHeader('In-Reply-To')
#end
#end
