Steen,

sorry for the delay in answering.


What delay? Since this is not a paid support-list, you are allowed to do other things than just wait for my stupid questions to answer. :-)


* Whitelist: Is it possible to use wildchars in usernames. I would
like to whitelist all mails from a certain domain, no matter which
user from that domain is sending. (Perhaps something like *.<remote-domain> ).

Yes, but in our CRM database we have approx. 1000 companies that must be on the whitelist, and mails from them must in *NO* way be considered spam. IMO entering and maintaining 1000 companies directly in the config file is not the correct way to do it.



And I would like to be able to whitelist a mail address for all my
users in one step. (For example by using a wildchar: *.<mydomain> )



This is a good idea, and I will add it to WhiteListManager and IsInWhiteList.
But what if a user ingenuously answers to a spam message to be removed?

Yes, I see what you mean. In my case these wildchared whitelists will not be maintained by the user himself, but come directly from the CRM database.


* Spam manager: Is it possible to automatically add a whitelisted mail directly to the corpus. This way my users don't have to send non-spam mails to the spam manager.



Again, you can do that just playing around with the config file,

I see the problem and I'll drop my idea.




* Spam manager: Are mails identified as spam automatically added to
the corpus. Again to save my users from sending spam mails to the
spam manager. (You know, my users are lazy)


Same as above, but moreover IMO it would be dangerous: the

I see what you mean and this idea is dropped too.
