   No, you can have several outgoing servers configured, but you need to   
   associate the appropriate server to each "incoming"/POP/IMAP account.   
      
   In Edit > "Mail & Newsgroups Account Settings", the top-level pane for   
   each "incoming" e-mail account has a drop-down box for "Outgoing server   
   (SMTP)" near the bottom. So select the Hotmail "incoming" account and   
   choose the Microsoft outgoing server in the drop-down box. (This   
   assuming you have all the outgoing servers already configured - if that   
   is not the case, you have to first go to the end of the list to   
   "Outgoing Server (SMTP)" and there add the ones that are not present   
   yet.)   
      
      
   (If you use multiple identities per account (see the "Manage Identities"   
   button), you may need to check all identities.)
