Why keep all your virtual domains on one machine? Take off 50 from the machine, and get another machine and add them to the new machine. There is no reason they need to be in the same location. >We are starting to see a definite need for a bigger >server farm.

Just put some of your customers on a separate web server. There is no need to sync things up or to do round robin DNS. Also, put all your dialup web customers on separate machine as well if necessary. Look to see who your busy sites are and divide accordingly. When you setup your virutal domains, just tell the customer to make mail.yourcustomersdomain.com their mail server, and to mail www.yourcustomerdomain.com the location to upload/publish their pages to. >How about scaling the mail servers? Where can I read up on setting up >multiple mail/pop3 servers? What is the best solution to do this. Look at a) more RAM, b) faster drives, or c) some sort of RAID solution. Try putting your mail spool on a separate drive, or dividing it up on separate drives to balance the load. Have a look at comp.mail.sendmail and some of the ISP mailing lists on how to hackup qpopper to put mail in subdirectories. Still, 800 pop boxes is not a lot. You must have a fairly slow drive. And a separate partition is NOT what you want... Separate drives... >Any help or refrences to books or URL's is GREATLY appriciated. www.dejanews.com mailling.freebsd.*,comp.unix.bsd.freebsd.*,info.inet.access for the groups you want to search. ---Mike Mike Tancsa (mdtancsa@sentex.net) Sentex Communications Corp, Waterloo, Ontario, Canada To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
