Mailscanner uses undocumented features of the mail server queue system (at least on Postfix). It's known to corrupt emails, especially on loaded servers. Some configurations can work out, but there's no guarantee and Postfix developers turn down any support request involving Mailscanner.
There are clean interfaces in most mail servers for email filters, Mailscanner chose to ignore them and its users can pay the price.
