Exchange 2007 Send/Receive Internally OK. Receive externally OK. Send externally not working 550 5.7.1
I am not having any problems with our exchange server internally with transport. E-mail flow from this network internal and external is working fine. When off the internal network and using an e-mail client on a computer or smartphone you can receive messages but cannot send. Error 550 5.7.1 I can't specifically find my problem in the forums or I am using the wrong search terms. This started happening yesterday and I do not recall making any changes to the MSEC. Any help would be greatly appreciated.

How have you restricted the Receive Connector that those SMTP clients are using? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Update: I can send e-mail off net to an internal e-mail address if that helps at all. But, cannot send to users on gmail, yahoo, etc. In organization config -> Hub Transport -> Send Connector Name: External FQDN mail.domainname.com Address Space Type: SMTP Address: * Cost: 1 Network: Selected: use Domain Name system DNS "MX" records to route mail automatically. Source Server: OurServer -------------------------------- Server Configuration -> Hub Transport -> Receive Connectors General: Default Server server.netname.local Network: Local IP Address(es): 10.6.0.40 Receive mail from remote servers that have these IP addresses: 0.0.0.0/24 ; 10.6.0.0-10.6.0.255 ; 65.125.108.0-65.125.108.255 Authentication: Basic Authentication Exchange Server authentication Integrated Windows authentication Permissions: All Checked: Anonymous, Exchange users, Exchange Servers, Legacy Exchange Servers, Partners Receive Connector 2: SBS Internet Receive FQDN: mail.domain.com Local IP Receive: 10.6.0.40 Receive Remote: 0.0.0.0-10.5.xxx.xxx ; 10.6.0.30-10.6.0.30 ; 10.6.1.0-255.255.255.255 If any of this helps. If not let me know where to find the info you requested. Thank you for the response so far!

Well, to start, what the heck is up with the 0.0.0.0 network in those receive connectors? Also, are the receive connectors expected to accept e-mail from the Internet (in general) or just from the 65.125.108.0/24 network? What about all the networks between 1.0.0.0 and 9.254.254.254? The next thing to look at is the SMTP Receive protocol log and see if your inbound connection is using authentication. If it isn't, and this used to work, check to see if the certificate you're using has expired. If it has the server may have stopped advertising the STARTTLS keyword. If you only allow basic authentication when TLS is used that'd stop your authentication and lead to those 5.7.1 errors. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP Not sure whats the deal with 0.0.0.0/24 connector. This is a new network to me. I renewed a self-assigned certificate on Nov 2nd when it expired. It's supposed to receive e-mail from the internet in general but I don't know how to check that or not. Should I open the receive IP range from 1.0.0.0-9.254.254.254? Where can I check the status of STARTTLS?-Sean Pilgrim

Thank you! I found the TLS Authentication box was unchecked as you mentioned and when I applied that the mail started flowing. You are my hero! Do I need to start a new thread for another issue or could you help me with one? our OWA login page will load but when I enter my credentials from the internal network I get: Outlook Web Access did not initialize.
