After creating and deleting a forwarder, I cannot create a mailbox with the same name as the "deleted" forwarder
I created an email forwarder called BLUE@mydomain.com. Subsequently I realized that what I really wanted was an email box with that name, so I deleted the forwarder in cPanel. When I attempt to create a mailbox with the name BLUE@mydomain.com. I get an error message "Error: The requested email address, BLUE@mydomain.com, conflicts with the mailing list BLUE@mydomain.com." - However, I already deleted that forwarder, and have verified that it is gone from cPanel.
Is there some kind of housekeeping task I need to perform to clear out the old Forwarder after I delete it? Like emptying the trash?
Problem Resolved with the help of InMotionHosting support. The issue was related to migration from our former hosting company. We had been using an email listserver there called MailMan. I had set up BLUE@mydomain.com as an address managed by MailMan at the former hosting company. MailMan is not offered at InMotionHosting. However, the migration of our content (full site backup and restore) to move from there to here brought along all the MailMan configuration and files.
The result was that I could "create" forwarders using that same address BLUE@mydomain.com, but the deletion of them wasn't complete. cPanel would show them as deleted, but because there was leftover MailMan directories for a MailMan managed mailbox BLUE@mydomain.com, the forwarder would keep forwarding. Also, we'd get a "local delivery failure" because that old MailMan mailbox was still on the system, but non-deliverable.
