I am curious in setting up the following (small scale) system: 1 Person emails me a message with a data file in the body 2 My system produces new file based on data received 3 My system emails the new file to the person I will have a university unix account to do this. Again, this will be a small operation, essentially for a few friends. I'm looking for free software that will install painlessly. It need not be powerful. I'm not looking to become a listserv expert, just to set this small thing up. I have considered procmail, and this may not be a bad solution. Still I have been told that other programs exist already tailored for these needs. Any and all help would be greatly appreciated. Please send email directly to me since I do not moderate this list.
