How can I see the current Database Mail configuration? Our SQL Server (2008) instance is configured to send mail and everything is working correctly, but I can't figure out how to view the existing configuration, in particular the SMTP server. 

From SSMS I can only start the configuration wizard, and I can't find anything online - plenty of info on how to set it up but nothing on how to view the current settings. 

How can I view the existing settings?
+1 to @jsauni for the wizard

You can also use the following system functions.

EXEC msdb.dbo.sysmail_help_configure_sp;
EXEC msdb.dbo.sysmail_help_account_sp;
EXEC msdb.dbo.sysmail_help_profile_sp;
EXEC msdb.dbo.sysmail_help_profileaccount_sp;
EXEC msdb.dbo.sysmail_help_principalprofile_sp;


The wizard is probably easier to follow but these will give you everything at once without having to go back and forth through the wizard.  I find it a bit cumbersome. :)
