1) How does the spamfilter work - is it based on SpamAssasin with Bayesian learning included? Spam filtering is very important for my choice, and i would like a server with the features included instead of setting up extra software for this.
2) What happends to mails concidered as spam?
I know that virus mails can be deleted or have the attachements deleted, but is there any feature of keeping virus/spam mails on the server (perhaps auto deleted after XX days), in case an important mail gets filtered?
3) Is there any way of specifying on a per domain basis, whether or not such features as IMAP, spam an virus filter should be enabled?
4) Is there any kind of white list that overrules the filters, rules etc.?
5) Is pop before smtp suppoted, or how is it avoided that people are sending spam through the smtp server?
6) Is there any way of temporarily disabling an account or temporarily setting it up for forward instead of an ordinary account?
7) is max message size on domain the same as the max total size of mailboxes on the domains?
Some of the features i'm asking for might not exist, but are there any plans of implementating any of them?
Sorry for the amount of questions, but i hope someone has the time and will be willing to answer them - thank you

I look forward to your replies.
