Hello Alain,

I reanalyzed our actual configuration and found that the problem is more 
limited,because when I send a mail via imp webmail then imp passes the 
mail to postfix and the antivirus.

The problem that remains is about drafts. When a user saves a mail as 
draft, then it is not sent but simply stored by cyrus. This way the mail 
is not scanned. The user can use the drafts as a file storage and then 
recall the files from another PC. Is there a solution for this case ?

Thanks
Andreas
