We've been doing this for a while now and it has saved us a lot of grief. Look up renattach on Google. It's an add-on to postfix/sendmail/etc. and runs on most unices. On Sat, 11 Jan 2003, Juan Mejia wrote:
Hello guys, Tired of users who refuse to think twice before running an attachment, I thought that it would help if the mail was downloaded from the institutional server to a box that would process it and change dangerous file extensions in the attachments to something like "Don't run/rename if not sure" (maybe "format.com.DRIS"). Yes, people still can run the files, but first they would have to save and rename them. This makes it harder to execute a file, avoiding the fast, thoughtless reaction of double clicking anything they see on the screen. Ok, googling the web I found that ashampoo mail virus blocker does this (do I need to say I expected this to be an original idea), the problem is that I would prefer a single machine processing the 20+ mail accounts. Although I don't know how, I'm pretty sure this can be done on my learning-toy-experiment-spare Linux box. Here are my questions: What's your opinion about changing file extensions on windows machines to reduce the threat of malware through e-mail? Do you know of some application that does this on linux? If there's nothing like this on linux, what should I start reading, searching, etc. in order to make it on my own? (I have no idea about e-mail on Linux. Also I realize I probably will never get to do it, but having a project in mind is the best way to learn about something new). Thanks in advance, Juan mailto:jmejia () uchile cl
