here's an interesting twist.. our network is connected by a frame relay connection and our mail server in our philly office can send to yahoo, and aol, etc. just fine but our mailserver here can't -----Original Message----- From: Lara, Greg [mailto:GLara@xxxxxxx] Sent: Thursday, August 12, 2004 11:47 AM To: [ExchangeList] Subject: [exchangelist] RE: can't send to yahoo.com http://www.MSExchange.org/ Luke, it could be a dns issue as Chris mentioned, but the www.dnsreport.com report for your domain indicated that you're an open relay. I don't know if Yahoo rejects based on that, but I wouldn't be surprised, given the volume of UCE they must process.

RFC 821 is pretty loose in terms of the semantic requirements of the SMTP "conversation," and your explanation clarifies very well why. I guess a discussion of the SMTP protocol is outside the realm of this list, but I'll let it suffice to say that until the more recent RFCs (such as 2505) carry more weight with software developers and administrators, or until a better protocol is developed, UCE will continue to plague us.
