Your points are excellent, and this one bears emphasis: On Thu, Jun 11, 2009 at 01:15:46PM +0100, Graeme Fowler wrote: > As a complete ecosystem, it's possible to make the MTA do some of the > rejections before ever reaching mailman.
On the sites where I'm running Mailman, the overwhelming majority of the rejections are done before traffic gets anywhere near Mailman. Some of it is handled by the firewalls, and some of it is handled by the MTAs, but the end result is that nearly all (well over 99%) of rejections are done in-band during the incoming SMTP connection. Anything that makes it past that and still looks dubious is held for moderator attention, and they are trained to handle it in ways that don't cause backscatter. ---Rsk _______________________________________________ Nanog-futures mailing list [email protected] http://mailman.nanog.org/mailman/listinfo/nanog-futures
