Hi, let me try to answer your questions:

• What is "ServerTasks=….,mailscan"? (I mean the dots!)
  
  
  
  A Placeholder for other tasks (like update, replica, router)
  
  
  
  
  
• In my "notes.ini" there is just an entry EXTMGR_ADDINS. What shall I do!?
  
  
  
  Add it to this line separated with a colon (",")
  
  
  
• What is "ACL"?
  
  
  
  Access Control List.
  
  
  
• Which parameters for DR.Web I'm needing to configurate the database?
  
  
  
  you need the drweb command line scanner (on windows drwebwcl)
  
  start it with
  
  drwebwcl/?
  
  and you will see a lot of parameters
  
  I will use
  
  /ARN/GO/HA/NM/SD-/UPN/WA-
  
  
  
  
  
• Does Dr.Web scan "directory" or "file"?
  
  
  
  Use "file"
  
  
  
  
  
• Which are the right return codes for Dr.Web?
