Sorry - I meant lockf. Exim was creating a lock file owned by the local user it was delivering to. If this file wasn't removed then access by a different user with appropriate group permissions did not work. The second user had insufficient permissions to remove the lock file and access the inbox. Obviously there was no problem with the owner accessing the mailbox. Configuring Exim not to use lockf cured the problem. Clive McDowell Information Services The Queen's University of Belfast
