Try flushing your DNS cache. If you're using Win2K DNS, flush it. If not, flush the dns cache on the exchange server using "ipconfig /flushdns" -----Original Message----- From: Stalin Peña [mailto:spena@xxxxxxxxxxxxxxx] Sent: 10 December 2002 1:23 PM To: [ExchangeList] Subject: [exchangelist] Yahoo domain. http://www.MSExchange.org/ Any time, that I send an e-mail from my exchange 2000 server to any user at the yahoo.com domain I get a non-delivery message. I'm able to send and receive e-mails from any internet domain. Is there any way that I can solve this situation. Thanks in advance!! ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: andreacoppini@xxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
