The question [I'll ask first] is why would mail to this specific domain not work? All other hosts work. And intellocity claims that they have no problems from any other mail servers. now the info:
I am having a mildy intermittent mail delivery problem, and for the most part it is non-working vs working.Errors that were discovered linking to Intellocity are as follows: Upon setting Maximum SMTP logging in Exchange 5.5 [I am at actv.com] - Event 3010 is being recorded in app event log -Event 2003 is also being recorded app event log 3010:An attempt to connect to host intellocity.com failed. Event ID 3010 can be caused by the any of the following scenarios: There is a name resolution issue to the relay host. There are limitations of the relay host, such as inbound connections are allowed. There is a firewall issue. To continue troubleshooting, run Telnet to determine if the IP address that is listed in the event is correct. Next, verify that the IP address has a functioning SMTP port. Event 2003: A new TCP/IP SMTP connection has been made to host 64.139.16.228 (for intellocity.com). Logfile: L0000004.LOG According to technet: If an event ID 2003 is reported, a connection has been made to that relay host. If you are experiencing event 2003 in addition to the other events, you may need to troubleshoot this issue as an intermittent issue. This event can occur if the maximum number of inbound connections to the relay host has been reached. I wanted to see where it was actually breaking down- So I went into the raw SMTP log files and excerpted the following: 9/7/2001 2:53:20 PM : <<< IO: |250 OK - Recipient <[EMAIL PROTECTED]> | 9/7/2001 2:53:20 PM : <<< 250 OK - Recipient <[EMAIL PROTECTED]> 9/7/2001 2:53:20 PM : >>> DATA 9/7/2001 2:53:20 PM : <<< IO: |354 Send data. End with CRLF.CRLF | 9/7/2001 2:53:20 PM : <<< 354 Send data. End with CRLF.CRLF 9/7/2001 2:55:03 PM : 499 Host unreachable: intellocity.com. Message subject: ""RE: Stock Options"". Rescheduling delivery for later. A technet lookup at this 499 error indicates: A 499 Error: "No routing hosts are reachable," indicates that the TCP connection has been dropped. My guess-obviously I am not a network engineer, is they are running some extended smtp set, like the cisco smtp fixup protocol or some outside factor is disconnecting them.? Please help. I tried to furnish as much info as I could.

We should document several tests to have on hand when we inevitably get asked what we've done about the situation.... An email to Derik with the tests we've done and the results we obtained would be wise as well. I don't want to say "It's not us" though until we're 100% positive..... _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
