None of the mail servers need any sort of "LVS" magic, and nothing about mail is really CPU bound (other than AV), and mail systems nicely distribute themselves when given the opportunity to. [1] we use mon, a custom alert script, and djbdns' tinydns. Very lightweight and failover is seconds. -- Ted Deppner http://www.deppner.us/

I would also like RM> to have Round robin with DNS etc.. We are using Linux Virtual Server to accomplish this: http://www.linuxvirtualserver.org/ Basically it involves 4 machines, 2 mail toasters using qmail, vpopmail, spamassassin, clamav, squirrelmail, 1 NFS/MySQL server and 1 load balancer. The load balancer does weighted round robin to serve POP3/IMAP/SMTP/WWW to the mail toasters. It also runs service checks to make sure those services are active, if they are not, it removes the server from the cycle. Setup is easy, the queue is local to the machine, the only thing that is mounted is /home/vpopmail/domains/, all of the qmail and vpopmail config and control files are synced to each individual machine off of the nfs server when changes are made via a perl script that we hacked up. User authentication is of course via MySQL. Oh, and the Squirrelmail software is shared via NFS also.

Thanks for your support Remo Mattei Network Security Engineer cell 801-808-unix email [EMAIL PROTECTED] In that case, I would build nameservers to point to 2+ mail servers under the same name. Bind can easily perform this round robin function...and is free. There are a load of howto's that can help...or I might recommend the O'Reilly press dns series. Also Google can find a LOAD of DNS info. If you are interested in load-balancing, I would try the information at http://lartc.org All this...if you are willing to build your own. Otherwise start contacting vendors that can do it for you. the toaster is designed to handle mail only. Perhaps this is not the right forum to ask of such unrelated matters. Once you have the load-balancing and round robin setupthen I would perhaps approach with the question of how to share mail between the server(s). Hope this helps direct you in the right place.
