SBS2008 SMTP SSL Cert is still using self-signed

After installing a GoDaddy SSL Cert to a SBS2008 box that prevoiusly had a self signed cert, I see that IIS and IMAP have taken on the new cert, but SMTP is still using the old self signed cert.

I have restarted the exchange transport service, but this has not helped.
Which service should I restart to force the setting?

Get-ExchangeCertificates shows the services are assigned to the Godaddy cert OK

Smtp should be able to use a self signed certificate. If you think the certificate is expiring you can simply run get-exchangecertificate <thumbprint of current certificate> | New-exchangecertificate.

Another alternative would be to run the Fix My Network wizard in the SBS console. It may detect and fix the issue.

It was Self signed, I have a new 'proper' SSL which I have installed.
If I run get-exchangecertificate I can see the correct thumbprint has services Imap, Pop, Smtp, IIS 'bound' to it

But, If I probe the smtp service

openssl s_client -starttls imap -showcerts -connect [server address]:25

then I can see that the old self signed cert is being returned.

Do I need to reboot the service, or restart a service to make the new cert 'active'?

Note: The 'proper' cert is being served to IIS, Pop and Imap.   Its just SMTP that is using the old cert.

Enable-ExchangeCertificate -Thumbprint <go daddy thumbprint> -Services SMTP

Then delete the old certificate
 Remove-ExchangeCertificate -Thumbprint <self signed thumbprint>
Press Y to confirm and you're done

Like I said above there are no issues with using the self signed it won't break anything. In fact most people use it for smtp.
