[Dbmail] high performance dbmail cluster

[alexander benaguev]

hi all
i have only two blades in bladecenter (2xXeon, 4GB RAM, fiber channel). 
so, i consider of this conception:
dual-master mysql as backend. set of dbmail-imapd or -pop3d at both 
blades as frontend, which connected to localhost. users and smtp-servers 
balancing between blades with round robin dns. i haven't any possibility 
to use third machine as load balancer or virtual server. i haven't any 
experience in clustering-loadbalancing too=) any criticism is welcome. 
thanks

alexander
