thank you very much for your reply, but it didn't solve the problem;
in filters - spam filtering, now I have the following situation
- enable spam filtering: checked
- bypass spam filtering when allowed relaying access: checked
- enable white list: checked
- reverse lookup=*@domainname.com
but the mails to this domain are still controlled by our Bayesian filter, and if someone sends spam (we ought to say: if the filter think it's spam) the mail is not accepted;
it doesn't seem to look at the white list ... why that?
thanks for your help!
