I've got a trial account - but it does not work out of the box (just dropping the URL of the mail server and name and password into the Server-Manager/Email/Email Delivery boxes).
Can you give me some more details of the changes you needed?
Here is my SME 9 test server setup - I'm debugging Bug 8060 at the moment and needed to set it up there.
Until Bug 8060 is released you need this line
config setprop smtp-auth-proxy Blacklist DIGEST-MD5
Here is my setup (not sure why I have the IP address and not the name, but it works)
Address of Internet provider's mail server 62.13.128.189
SMTP Authentication for Internet provider Enabled
Mail server user id username-from-authsmtp
Mail server password password-from-authsmtp
And if you check from the shell
smtp-auth-proxy=service
Blacklist=DIGEST-MD5
Debug=enabled <-- not needed
Passwd=password-from-authsmtp
Userid=username-from-authsmtp
status=enabled
