My company needs a new mail server. This server will support various automation and workflow concerns as well as a light volume of customer mail. It will be supported by my customer facing organization rather than the Enterprise IT organization, so I have convinced the decision makers to let me stray from the IT standard of Microsoft Exchange. Though I suspect the volume of mail to be light, it must still be a highly reliable system. I would love to be able to make the case for migrating the entire company away from Exchange someday.
My thought is to use qmail along with qtrap, clam av, and spam assassin. I'm leaning toward qmail since I know it to be simple to set up and administer. That's important since there will be no dedicated mail jockey. I am also interested in running a second mail server, not for load distribution, simply for redundancy against failure. This is where I have the most questions. It seems clear to me that setting up two hosts as mail exchangers and sharing between them via NFS is absolutely not what I need, yet this is the solution I'm turning up when googling for redundant qmail. The only way I can imagine this working is if NFS were offering a file system from a 3rd reliable location to each of the two hosts. Does anyone have a good suggestion for me to create some redundancy using only two hosts? FYI the hosts themselves are solid hardware with mirrored disks. I also have LVS directors in place so that option is definitely on the table in addition to MX record tricks if I can just determine how to get the same data on both hosts. I'm also open to suggestions other than qmail if there is a good redundancy story specific to some other solution. -- TriLUG mailing list : http://www.trilug.org/mailman/listinfo/trilug TriLUG Organizational FAQ : http://trilug.org/faq/ TriLUG Member Services FAQ : http://members.trilug.org/services_faq/ TriLUG PGP Keyring : http://trilug.org/~chrish/trilug.asc
