Hi there,
First off, sorry for the wordy subject 
The ITSM solution we currently use has a mail monitor built into it that takes emails and breaks parses out various elements into variables that we can use to create specific tickets.
For example we have structured our system generated alerts to have particular words in the subject to steer the info to a ticket type and we have delimiters in the Body of the email to be able to pull out words, dates, information
i.e. we can derive the host name due to having based on a rule that says within the body of the email After Hostname: and before <<end Host name it will start the value.
We are getting emails for off boarding from our HR system and through our scim connector we can totally format the email.
I want to be able to capture things like the user name, their account name, end date, notes that are all formatted in the email to be parsed out. I am just not sure who to plug all this in to JSM to be able to catch the email, pull out variables and then to create the 'Staff Movements' ticket we have as a standard request type.
Thanks.
