I'm out of my league in estimating the hardware side of things, but on the webmail front I would seriously reconsider using HORDE/IMP. Having evaluated it, I can say that: - It is a resource hog both in terms of memory consumption and CPU cycles. - It is insecure, as it is prone to XSS and session hijacking (mainly due to Javascript, but also due to the fact that you need to enable fopen wrappers and register globals to make the darn thing work). - It lacks good input validation and I don't really see the point in using an RDBMS in storing user settings and the like. - It suffers from featuritis and a plethora of half-finished components. If all you need is a webmail client, I would recommend that you take a look at Hastymail, which is fast, RFC compliant and a lot more secure than IMP or the like. Combined with Cyrus, Exim and Slapd it has the potential for a killer app (IMHO).
