Thank you. Wow. My server is running the same version. Either mine uses a different configuration or my server handles a tiny portion of the quantity of messages that your server receives. My email server is basically a spam trap; most messages to my server are forwarded into another program so the "write message to filesystem" is never called. We receive a few thousand spam messages per day and maybe 40 real messages per year. solprovider --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
