Does anyone have any stats on the relative performance of Scalix / Zimbra / OpenXchange? I switched to Scalix from cyrus a while back to get the extra functionality but it seems to cause our server to run very slow at times and hogs RAM like it's going out of fashion. It's not a small box either, 8GB RAM, terrabyte HD, two quad core processors and I've only got 10 mail users on it. -- Kevin Thorpe Head of IT Purchasing Index Ltd
