We are using JSM server mainly for internal support and all of our internal customers have an account. We are also using e-mail requests. However, sometimes external clients contact us (by e-mail). We do not want external clients to have accounts in our jira instance (as our jira instance is not accessible from outside anyways). So, when an external client sends an e-mail, the reporter should be set to a default reporter. This is possible if a add an e-mail handler for a software project, but in service management mailhandlers, there is no such option. So should I create a standard-mailhandler and link it with the service management project instead of using the e-mail channel option right in the project (which is basically possible) or is there another approach to deal with that usecase?
