this all appeared in test-messages with 1 sender and 1 recipient. in the log-file, i only see one line: Jun 11 12:14:35 mail courieresmtpd: started,ip=[::ffff:209.69.178.212] this is a blacklisted ip-address in ordb, which allows even simple relays. but when i tcpdump the interface, i see a lot of smtp traffic. armin _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas - http://devcon.sprintpcs.com/adp/index.cfm?source=osdntextlink _______________________________________________ courier-users mailing list [EMAIL PROTECTED] Unsubscribe: https://lists.sourceforge.net/lists/listinfo/courier-users
