Email Transport Filters

Filters can be set on an endpoint to filter out any unwanted messages. The Email transport provides a couple of filters that can either be used directly or extended to implement custom filtering rules.

Filter Description

A base filter implementation that must be extended by any other mail filter.

Applies a regular expression to a Mail Message subject.

This is how you define the MailSubjectRegExFilter in your Mule configuration:


       
    
1
<message-property-filter pattern="to=barney@mule.org"/>

The 'pattern' attribute is a regular expression pattern. This is defined as java.util.regex.Pattern.
