X-Virus-Scanned modification

[Oleksii Krykun via amavis-users]

Hi,

by default X-Virus-Scanned is defined as "$myproduct_name at $mydomain".
I would like to specify real AV scanner name here. Is it possible?
Which configuration variavle responsible for this?

Scanners are defined in @av_scanners and @av_scanners_backup but how to determine which of them is really scanning message and put it's name into $X_HEADER_LINE?

Thanks,
Oleksii
