If that's your limitation, then I fear you are doomed to minimal filtering. The kinds of strings that you could potentially catch in junkmail change too quickly, and there's too much of a chance of a "false positive" (where something gets tagged as spam when it's not). I use Eudora myself, and my filtering is relatively minimal. First off, I look for certain e-mail addresses belonging to certain people that I know I don't ever want to hear from again, and that stuff gets tossed in the trash. I then search for the mailing lists I know that I've subscribed to, and they all go off into their respective folders. I then look for anything that actually has one of my e-mail addresses listed as one of the recipients, and then depending on which e-mail address it is, that either gets filed in my "home" or my "work" folder. Everything else (basically, anything sent to me from an address I don't recognize, and for which I am only an envelope recipient) will get left in my standard "inbox", which I have to sort through manually. I don't think that you can realistically expect to do much more than this with the kinds of simple filtering available in Eudora, or somesuch. -- Brad Knowles, /* efdtt.c Author: Charles M.
