Aha. Yes, I see what you mean - anything that the downstream MTA can validate goes out using a connector set to "use DNS", which will end up in the same MTA because the MX records will take it there, and fails here will not cause link-downing. BUT - what about the case where a user types a syntactically-invalid address? Something like "[EMAIL PROTECTED],com" (note the comma). That will also get a 550 response from the MTA and trigger a link down.... _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang=english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
