I'd like to create multiple rules for the email handler so it creates a new issue on the project specified for the sender of the email.
For instance: when user A sends an email it should create an issue on Project A and when user B sends an email it should create an issue on Project B.
Right now an issue is created on Project A, regardless of wether user A or B sends an email.
Emails are sent to: jira@mycompany.atlassian.net
The built-in email handlers simply cannot do that. They are mapped by email address -> project and issue type. They can't process based on anything else.
You'll need to have a look at the more advanced mail handler apps in the marketplace, I suspect they may be able to do what you need.
