I set up dual email servers feeding into a a request ticketing
system which used established 'queues' to automatically sort incoming
email into areas such as support, security, notifications, etc. This
enabled our small staff to provide robust client coverage.
The
queues were further divided into client areas, so that time and
resources could all be maintained within one threaded chronology.
The system provided feedback to the client that their tickets
requests had been received and any correspondence ongoing on the
particular thread.
Also provided time and priority system so
that resource allocation could be tracked per ticket or client.
Coordination of work activity on any request could also be done with
the system.
