Thanks Chris! Is there anyway to make this happen, to make Exchange pick a specific SMTP server for a domain to deliver email to? If so how?

Make sure you have the latest OS hotfixes/patches, Exchange/IIS should attempt to failover to higher priority Mx records if they receive that response. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Alborzfard, Alex Posted At: Friday, November 11, 2005 10:15 AM Posted To: swynk Conversation: 421 SMTP Service not available Subject: 421 SMTP Service not available Outgoing emails to a certain domain do not make it. When I try SMTP to recipient domain's primary MX mail server, I get the following: "421 SMTP service not available, closing transmission channel" There is Barracuda Spam server in place, but according to Barracuda it's not filtering outgoing emails. I looked into logs, but cannot find a trace of the message(s). Any ideas? --Alex _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/read/?forum=exchange To subscribe: http://e-newsletters.internet.com/discussionlists.html/ To unsubscribe send a blank email to [EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
