In response to JEMH-109, here is a quick checklist you can use to help verify you've read the instructions.

Checklists

JEMH Mail Handler

If you have upgrade your JIRA, be aware the packages changed a long time ago, the prefix is now 'com.javahollic.jira', check your popservice.xml / imapservice.xml files...
You have downloaded the correct JEMH Jar for your JIRA version
You have extracted the example-emh.properties file from the JAR, and saved as WEB-INF/classes/emh.properties (or whatever you like, you'll refer to this later)
You have read the User Guide and understand what the configuration file needs to have enabled /is appropriate for your system
You have added the ldaputil JAR and ldaputil.properties file if you use LDAP for user email address -> ID lookup
You have updated the imapservice.xml/popservice.xml file to list JEMH
You have created the POP Server and selected the Jira Extendable Mail Handler as the appropriate handler (requires a restart after previous step to show up). Setting a forward=youradmin@yourco.com is a good idea to get notification of unprocessable mail. NOTE: Trying to add JEMH as a Service is not possible, follow the install guide more closely!
You have set, in the handler.params, the mandatory configFile=xxxx.properties referred to in step 2. Not doing this will currently result in a NPE.
