It sounds like they were. The envelope sender of the autoreply system will most likely still be the same as the user it's autoreplying for. Also, auto-whitelisting like TMDA where you need to reply to a specific magic address to get your mail into the whitelist for a while don't send DSN messages, as far as I've seen, just a typical autogenerated message. > If you pick addresses by any other means to autorespond to, then > you're just asking for trouble.

We're not talking about the same message being ping-ponged back and forth, we're talking about an email that triggers a script that sends a -new- email back, which triggers another script, etc, etc. New headers each time, so X-Loop would vanish at each end. But yes, this isn't a SA thing, it's a detecting when automated scripts are nattering at each other. _______________________________________________________________ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas -- http://devcon.sprintpcs.com/adp/index.cfm _______________________________________________ Spamassassin-talk mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/spamassassin-talk
