Hm... it is complex on the server side, but it looks rather simpler for an occasional interface writer, as not every callback has to be implemented.

Yes, well, that is possible with the whitelisting API. However, it is cumbersome to interface both APIs within the same piece of client code. Minor adjustments may make that simpler.

For example, there is a commercial antivirus product that only supports libmilter (Avira). In addition, having, say, a native courierfilter that emulates libmilter would put Courier neatly ahead in a filtering features comparison. ------------------------------------------------------------------------- Take Surveys.
