Hi,
I have been searching all day and cannot find anything exactly.

ISP change this morning to upgrade line. All config the same except modem would not do NAT so we made it transparent and added PPPoe to our Juniper router. Juniper otherwise is the same as before.

We can receive email, but no SMTP except internal and no OWA.

Default connector has TLS and basic, permissions are anon, exchange users and servers.

DNS tools say SMTP is OK.

telnet works with mail from but on rcpt to it always says unable to relay.

exchange troubleshooter said it could not get a remote socket.

logs say failed connection and queue says retry on all.

I am getting tired now and our client is a city agency been down all day.

Any help would be great!

Every article I see is about wanting to relay. I do not, I just want the Exchange server to send its emails :)

Did you remember to update your SPF record and did your ISP update your RDNS entries?  If your IP changed did you update your host record in Public DNS for OWA?

OK, so after being on the phone and proving to Qwest port 25 was blocked. The engineer blocked then unblocked port 25 and mail flows!
