Virus Scanning in GroupWise
By Claudia Lynch, Benchmarks Online Editor
According to Andrew McGregor, the "Tips on GroupWise" guy, and Jason Myre of the CWN Messaging Support Group, a new virus scanning E-mail server has been implemented for GroupWise. Called Iatro (pronounced ya-tro -- the Greek word for doctor), it is currently checking all incoming E-mail destined for GroupWise mailboxes. All outgoing GroupWise E-mail is also being scanned. According to the CWN folks, this is necessary because of the unique way GroupWise encrypts its E-mail and handles attachments.
How can you tell your mail is being scanned by Iatro?
If your mail is being scanned, you will notice an additional hop in the mime header. For example:
What if a virus is found?
If Iatro finds an infected E-mail message, it will not route it, but rather send a notification to both the sender and recipient (Note: An intended UNT recipient will not be notified if the sender's address is also from UNT). Below is an example of the notification message that the sender receives:
Similarly, if someone attempts to send you an infected message, you will receive something like this:
Finally, here is the message you will receive if you attempt to send an infected file, via the Internet, to someone else on campus:
No more virus worries then, right?
Although this adds another layer of protection to the University's network, Iatro is not the be-all and end-all solution. It will not intercept viruses that are propagated by removable media or from downloading files from the Internet. Iatro only scans E-mail that comes in from or goes out to the Internet. Internal GroupWise mail is not scanned. You are urged to continue to run virus detection programs and maintain up-to-date virus signature files on your machine (this should be done automatically, see your network manager for more details).
