Repeat virus upload notification issues

I am running Mahara 1.0.2 on Ubuntu 8.04 Server (Apache 2.2.8, PHP 5.2.4 and MySQL 5.0). I have the latest version of ClamAV. I am using Postfix running on the box to rely mail to our campus mail server and this is working, as users receive notifications of new personal messages.

I have set 'repeat virus upload notification' to 'email' in the 'Activity preferences' section, and I have tested that ClamAV works by using eicar and I am sussesfully prevented from uploading the file.

Is it possible to set the number of attempts that is classed as 'repeated attempts'? For example initially I would want an email everytime somebody attemps to upload a file with a virus. After testing I may want to reduce this to only email after 4 or 5 attempts.

During the testing with the eicar test file I was prevented from uploading the file each time I tried it, but never received one notification about repeated uploading.
