My organization is moving to Jira service manager cloud from a different ticketing system. We will primarily be receiving issues by email and given the nature of what we do, some of those requests will come from external domains. At the moment service manager cloud sends an account verification email any time someone emails in for the first time. We would like to disable the need for that verification. I have seen in other posts that it is possible in the server version. Is this possible in the cloud version?
