Also, an entry like: NOQUEUE: Null connection from host.domain [IP.AD.DD.RESS] in the logfile means that host.domain connected to your MTA but neither initiated transmission of a message (by issuing the MAIL command), nor used any of the commands that are logged separately (EXPN/VRFY/ETRN). Unless this happens very often, you can ignore this. If it happens very often, it's either someone playing around or it's a network problem. -- Tony Green <[EMAIL PROTECTED]> Tel : +61-(0)2-9500-9996 Mobile : +61-(0)4-2521-9996 GnuPG Key : 1024D/B5657C8B Key fingerprint = 9ED8 59CC C161 B857 462E 51E6 7DFB 465B B565 7C8B -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
