I'm looking for a web based test to see if my machine is an open relay - BUT I need a test that doesn't blacklist me anywhere. I just want to make sure, and if I am fix the issue ASAP. And also - since I am pretty new to exchange - how does one seal up an exchange server from being an open relay? ------ Dustin Krysak _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
