I've developed a sudden interest in whether an inability to DCC send files while being entirely able to receive them when everything at your end is configured correctly has much to do with the written policies of any ISP/School/business/etc. or is just unintentional/incompetent configuring at their end.
My guess is that an overwhelming majority of cases would be the latter, but it is only a guess, so can anyone quote references forbidding the use of passive mode to send files, either application specific, or regardless of the application?
