Imagine a heterogene network environment with both UN*X and DOS / Windows/ Macintosh workstations. Now think of an UN*X server that serves Windows and/or Macintosh workstations via a POP3 service. Would it not be nice to ensure attachments coming via email are scanned for viruses before they reach a system they are able to infect? Well - that is what this package is for. It resides on the server that handles your incoming mails. When a mail arrives, instead of being delivered via procmail directly, is parsed through a script that extracts all attachments from the mail, unpacks (if needed) and scans them using a professional virus scanner program. This is a perl implementation of the mailscan.
