I believe it should use the secondary MX if it can't connect to the primary. Your problem is because it actually connects successfully and then drops the connection because of their [mis]configuration.
Sincerely, Andrey Fyodorov Systems Engineer Messaging and Collaboration Spherion -----Original Message----- From: Durkee, Peter [mailto:[EMAIL PROTECTED] Sent: Monday, September 08, 2003 7:28 PM To: Exchange Discussions Subject: Delivery to Alternate MX Records Hi All, I'm a bit puzzled by something and I'm hoping that someone can help out. There's a particular domain, seanet.com, that we can't send messages to at the moment. Any message sent to this domain hangs in the IMC queue with the error, 452 4.3.0 Cannot write message to disk. According to this ISP's support group they've recently reconfigured their main mail server so it can no longer receive messages from the outside world, and I assume that the error we're seeing is a result of this reconfiguration. They further claim that our server should try to deliver messages to their second or third mail server, something it definitely isn't doing. So here are my questions. Should an Exchange server (5.5, by the way) try the next MX record after getting a 452 from the primary server, and are there any settings in Exchange that affect this behavior? As an additional philosophical question, does it strike anyone else as strange that they should deliberately put an essentially malfunctioning server at the address of their first MX record in the name of spam fighting and security? -Peter ______________________________________________ This message is private or privileged.
