Define "too many users" please. NFS has been used. Read Nick Christensen's (1997?) paper on the Earthlink setup. www.jetcafe.org jumps to mind. While I've written software to do it, qpopper with the monolithic spool file doesn't really scale well to millions. Other tools have matured in the last year to go really big. OTOH, with current machines an a good IMAP server, I've put 200,000 users on a machine. Sendmail Inc's IMAP server has tested several million on a single S/390 with Linux. You alphabetic scheme has several problems. Since it's not part of qpopper, it's not relevant here. > I've been thinking about this and believe the best way to do it would be > based on the first character in the local-part of the e-mail > address/username > > i.e. mail to a*@domain.com to j*@domain.com goes to server 01 k*@domain.com > to z*@domain .com goes to server 01. > > To do this I presume you would need at least three servers 1 being a forward > machine and the other two being physical mail hosts. > > Obviously I would need a SMTP splitter of some sort, any recommendation > would be good to delvier mail based on local part of the e-mail address. > > Then I would need a pop3 splitter to be able to bounce you to a seperate > host based on the username?
