You could still use your ISP email server as a smart host. I have something similar. ISP--------(business broadband)-------ISA 2004------ Exchange 2003 sp1 Exchange is configured to use the ISP's smtp as a smarthost. /Gill -----Original Message----- From: Musser, Dale [mailto:musser@xxxxxxxxxxxxxx] Sent: Saturday, September 25, 2004 2:44 AM To: [ExchangeList] Subject: [exchangelist] Understanding about dns and exchange http://www.MSExchange.org/ OK I must be new at this because I am lost. I have no idea where to go next. This is my problem. We have a new exchange 2003 server installed and I am having the same problem with multiple people. Some emails come back as failures because the virtual SMTP server can not confirm the dns examples : yahoo and aol. I liked the days when we just sent all emails from our company to our internet providers smtp and let figure this all out but instead we send directly. I can look at the queues and see failures like yahoo.com and 3 emails trying to get out but no good. There must be something I am missing here, I have been reading books and doing searches on the internet and nothing. Help!!
