No, it's fine. I've built NFS clusters with multiple machines for receiving incoming mail [exim/deliverquota], for POP3/IMAP [courier-imap], and sqwebmail, all talking to the same maildirs. > The cache is held on > the server itself.

If you are sharing the load between multiple front-ends then you should configure your load-balancer into 'sticky' mode so that repeated connections from the same IP address hit the same webmail server.
