Microsoft Exchange Relaying Problems
Version of Exchange would help. However the primary reasons for this problem is either missing anonymous on the SMTP/Receive connector, or missing domains from Recipient Policy/Accepted domains list. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.

Hi Simon, It's 2003 I'm running. As far as I can see, these are set correctly. Could you give me a rundown what they should be set as so I can check them against their current setup though? Many thanks. Alan

Hi there, I have a problem with the Microsoft Exchange Server in our office. We are having ALL inbound external emails bounce and the following message given to the senders: 550 5.7.1 name@domain.com... Relaying denied I've seen similar posts on here before, but they seem to relate to outgoing mail, and in this instance the opposite is happening: - ALL incoming external mail is being rejected (on all of the email addresses for this domain). - ALL outgoing email traffic is operating normally from all PCs for this domain. - ALL internal email traffic is operating normally from all PCs on this domain. I've already checked the correct IP address is in place for the mail.domain.com in the DNS settings and that the MX records are set up correctly. Can anyone suggest anything else to try? I'm stumped. Many thanks.

Its exactly as I wrote above. You need to look at the properties of the SMTP virtual server in ESM to ensure that anonymous is enabled on the authentication settings, I would also check the connection properties to ensure that no restrictions are in place on what can connect to the server. Recipient Policies again, exactly as I wrote - the domains the server is serving email for should be listed. Everything is documented all over the internet - the process hasn't changed for at least nine years. Simon.Simon Butler, Exchange MVP Blog | Exchange Resources | In the UK? Hire Me.
