Users are getting created from ignored emails when property 'glide.pop3readerjob.create_caller' as it is set to trueSummaryUsers are set to automatically get created from system property glide.pop3readerjob.create_caller as it is set to trueSo an incoming email can create a user record automatically. But, the emails which are ignored and moved to Junk due to postmaster and mailer-daemon in headers are still creating the user record, so if the emails are not processed due to the email filter then why the user accounts are getting created from junk emails? Servicenow Email Inbound processing occurs in two steps: 1) Creating sys_email record from Email MIME object and providing necessary access to the related user.2) Run Email Filters and Inbound Actions/Triggers Steps 1 and 2 are processed in two different threads.Since the 'glide.pop3readerjob.create_caller' system property is set to true and it will always create the required user in step 1.Execution of email filters and marking the respective email as ignored happens in step 2.This is expected behaviour from Servicenow Inbound email processing.Related LinksLink to docs: Enable automatic user creation
