We have several monitoring services that send notification e-mails when their alerts are triggered. In case of major incidents, many e-mails can be sent in short amount of time.
Notification e-mails from each monitoring service are sent to per-project mailing lists, to allow for easier configuration — when you have to subscribe a new employee to the list, you can do it in one place.
We're (ab)using google groups for notification mailing lists, but we want to move to a self-hosted solution.
Please advise, what mailing list management software would suit our needs?
Requirements:
- The solution must be redundant — we should be able to set it up on at least two physical machines, with shared configuration.
- Web archive is not necessary, but all e-mails must be stored on server, just in case.
- Open source is preferred.
Note that I say "mailing list" above, but, maybe, something simpler would do? (Like a properly configured forwarding e-mail address...)
