First of all, thanks again for this great mail server!
Now, I know Spamassassin is supposed to work with Scalix out of box etc, but Spamassassin isn't the easiest to monitor or manage without third party tools. I have ended up using MailScanner and MailWatch to configure and monitor all my antivirus and antispam problems. The problem with this is that it wasn't self-explainitory and it is still needing some tweaks here and there. It would be perfect if in the future there was more integration between Scalix and Spamassassin, where you can configure rules, whitelists, etc easily.
My next suggestion is related to the first. I have used several webmails in the past where there is a nice and easy "Report as spam" button, where you can easily get rid of a spam message that got in your inbox, and it is then taken into considerations for spam in the future. I would love to be able to have this option in the SWA, or even the Scalix Connect for Outlook/Evolution. Right now I'm trying to figure out a way for my users to easily move any spam emails into a special folder (named "Junk E-Mail" of course) that are spam, and then I hope to be able to make a scheduled job that takes those emails, adds them to the Spamassassin Bayesian filter, and then sends them to DCC, Razor, or Pyzor (or something along those lines). It would be great if there was just a button that they could press to put all the junkmail on the whole server into the one folder, and then I can have it process that one folder, instead of a single folder in every user's mailbox.
If anyone has any suggestions on how to do this easier, please let me know! In the mean time, please take this as a suggestion for Scalix 11.5 or something (I'm sure this is too late for Scalix 11 as it's already almost into RC1 phase... but if you can add it in, great!).
Note: I realize that you don't want to lock customers into using Spamassassin, and that you want to leave it open for users to use any spam protection they want, but I don't see a problem in providing maybe an optional installable module or something that will work with it. Thanks!
