Or, will DCC have to conform to each MTA's filtering protocol as it has for sendmail? I think the latter is more likely. One benchmark to look at may be virus checkers. Many of them offer to act as pseudo SMTP servers -- either in front of the real MTA or behind it in a filtering step in the SMTP chain. This is an example of a class of application with needs similar to DCC that has failed to foster a universal content filtering protocol (beyond SMTP itself). I've chosen to let the other issues we were talking about (suitability of SMTP as an interface, where bottlenecks are, etc.) drop since the above is really the crux of the issue.
