Quarantine doc Files only with Macros?

Sorry! This was my fault. As I wrote

But I didn't notice (the filesize was the same as before). The word 
macro was a virus, which was not recognized by antivirus program at the 
beginning.
Later I had performed a test with Outlook and IMAP and the antivirus 
program cleaned the mail in the imap folder of one server. But the file 
was still attached to the mail and seemed not to be changed the macros 
were deactivated anyway. So only only mails from the other server 
actually contained macros.

Today I tested with a another file with macros and all mails were 
blocked from both servers. Sorry again for this confusion.
