Need: HA Qmail Cluster Services & Webmail
Anyone know of any relatively simple to follow instructions or ready made systems for building a Linux HA Qmail server?
I'd like to have a cluster at the main location as well as at least one backup server on another network for redundancy.
Also, fro your own experiences, what do you think you use for bandwidth to provide email to some 2000 to 4000 users? And what do you use to keep it fast as well as reliable?
Thanks much.
Mike
