I get the same problem and in 3 days time I will get the full NDR mostly from AOL so I don't think this is an aol problem (especially as if I use a webmail account with the ISP it goes through) I am fairly certain it is a configuration issue ND -----Original Message----- From: Lara, Greg [mailto:GLara@xxxxxxx] Sent: 11 August 2004 19:18 To: [ExchangeList] Subject: [exchangelist] RE: can't send to yahoo.com http://www.MSExchange.org/ You wouldn't. That error indicates that the message was received, but not yet delivered to the recipient. It's quite possibly an internal problem that yahoo or the recipient is having, and has nothing to do with your configuration.

A lot of admins (damn newbies) don't know to set their SMTP FQDN to the same as their MX record in DNS, which is cause for an increasing number of ISPs to reject mail, and for good reason.

It turned out to be DNS issue reverse DNS lookup issue. Once my ISP corrected this we could send to our AOL clients again.
