Hi, - Integration of rrdtools (or mrtg) will be great ! - A very very simple and customisable interface for clients, with only possibility to modify password, add/remove auto-responders and mail filter, view stats. - Better spam handling. For example, possibly for the client to add spam in a spambox, automaticaly scan with the sa-learn spamassassin option (just a cron on the spambox). And, why not, a low/high score spam deliver/delete. After this, it will be perfect
