Until now, the IWI has had its own mail servers, equipped with spam detection, anti-virus measures, local delivery with procmail enabled, and IMAP and POP services to retrieve mail from. It also kept its own mailing lists. Unless significant effort is put into buying and configuring new servers, this situation cannot persist for much longer, as the hardware is long out of service, and the people who supported the server have been reassigned to other tasks. This document tries to plan the moving of users' mail from the old IWI server to the present CIT servers, and lists the changes that users will experience.
