Thanks to a tip by Anatoliy Mogylevets I found out the following, which I pass in case it's useful:

1) HKEY_CURRENT_USER\Software\Microsoft\Internet Account Manager\Default Mail Account contains the internal name of the default mail account.

2) HKEY_CURRENT_USER\Software\Microsoft\Internet Account Manager\Accounts\xxxxx\SMTP Server contains the SMTP Server name, where xxxxx is the internal name found in step 1
