With dialback, this may not be an issue. Consider that it is not cost-effective for spammers to use a legit return address (bounces, complaints, tracking). This is part of the reasoning behind challenge-response whitelist email filters. There is a FAQ about such systems that asks: "What if the spammers respond to the challenge?" Answer: "They won't, because they will never use a legit address!"
Of course, the weakness with these whitelist systems is that a spammer could spoof the address of someone in your whitelist. This is not possible with Jabber, as there is no whitelist. Every s2s connection is authenticated. -Justin On Saturday 21 June 2003 04:08 am, Bart van Bragt wrote: > I was adjusting my email spam filters, again, and that started me > wondering about Jabber and spam. > > IMO there are not many provisions to prevent spam from being > sent/received in the jabber protocol.
