I am certain I do not have multiple pop3 servers or file shares. Nor do I believe there could be multiple instances of the ipop3d accessing the file since I have a controlled test on my workstation with one mail client running. However, this is my ipop3d configuration from xinetd service pop3 { log_on_success += HOST DURATION log_on_failure += HOST bind = 127.0.0.1 socket_type = stream user = root server = /usr/sbin/ipop3d wait = no }
