Delete unused SMTP servers in OS X

I had numerous unused SMTP servers in my  Apple Mail list, so I decided to tidy up and found the following steps do it (yeah!):

1. Access the Finder menu and navigate to Go to Folder and type /Library/Scripts/Mail Scripts/.
2. Look for Manage SMTP Servers.scpt and open it.  (This should open the Script Editor.)
3. Hit the Run button, then select the (SMTP) servers you want removed.
4. Hit OK and a message stating the deletion was successful should pop up.

That’s it, now when you go back to Apple Mail you’ll see a nice, pruned list.  BTW, you will only be able to delete SMTP servers that are NOT in use by any of your mail accounts.
