qscan is a sendmail queue scanner designed to scan all incoming email for file attachments and rename any offending file attachments. File attachments are not scanned for viruses, but allow you, the system administrator, to rename either some or all incoming file attachments to .txt file extension. The original filename is renamed to "filename~doc" for example, so that the end user can rename the file once it is scanned for viruses. Therefore, you will need to maintain current anti-virus software on your workstations in case a virus infected file is emailed to one of your users and they rename and execute that file.

This program is by no means a perfect solution, but if security is properly maintained at your organization it will allow you much greater flexibility at stopping any possible email virus outbreaks.

Unix system, tested on Red Hat Linux 6.x and AIX 4.3.1. It may run on Windows NT, but some modifications will have to be made. If there is enough interest in a Windows NT port, I will include future support.

Sendmail 8.9.3 configured to queue incoming mail. qscan should work with pre-8.9.x or post-8.9.x versions of sendmail, but it has not been tested.

Perl 5.005. Older or newer versions of Perl may work, but have not been tested.

Current production version of qscan is 0.1.2.
Update (2/12/2001) - Version 0.1.2 does have problems in high volume environments. Given time I will update the code.

Latest version of qscan is available here.
