You're barking up the wrong tree. You should have the multiple servers share the partition with the spools through NFS, then change the hostname that your pop users have been using to be round-robin DNS with entries for each of the real machine names. That's what the larger ISPs do. ------------------------------------------------------------------------------- Kim Scarborough http://www.unknown.nu/kim/ ------------------------------------------------------------------------------- "Everything's entertainment in America eventually." -Tracey Ullman -------------------------------------------------------------------------------
