7/9     Is there a way to bounce mail from certain sites (ie. .forward?
        .filter? .bounce?)? Someone is subscribing my name all over the
        place. Thanks.
        \_ procmail --aaron
           \_ http://www.dcs.ed.ac.uk/~procmail/faq/links.html --smitty
           \_ the problem with using procmail to bounce certain spammers
              is that spammers frequently switch email addresses (even
              though they usually don't exist).
                \_ There are a lot of things you can do with procmail other
                   than filter on specific addresses.  For one thing, you
                   can bounce all mail from invalid addresses.  -tom
                   \_ How do you do that?
                                in the body to /dev/null -alanc-
                           \_ http://www.dcs.ed.ac.uk/~procmail/faq/links.html
                   \_ COOL! How do I do that tom?
                           \_ http://www.dcs.ed.ac.uk/~procmail/faq/links.html
                        \_ or file all mail containing "EMAIL MARKETING WORKS!"
                                to /dev/null -alanc-
        \_ the spam revenger. Once you've found the email address of the
        spammer send a giant email which might bring down the remote
        system.
        #!/usr/bin/perl
        open(MAIL,"| mail spammer@spammerdomain.xxx");
        for(i=0; i < 99999999999999999999999999; i++) { print MAIL "fuck
           you\n"; }
        close(MAIL);
        \_ This is really stupid.  Most spammers use fake email addresses
           anyways (usually of prominent anti-spam activists) so it is
           more likely you will just end up mailbombing someone innocent. -mel
           \_ If you cant trace it and they're advertising something, you
              can do a whois on the domain and mailbomb them!
           \_ Are you sure they are not using their own addresses?  Think
              opposit.  Maybe they just want people to back them up.
           \_ Call their number, and get them to tell you where they actually
              located. It's not that hard, I'm sure you can think of a way.
              Then get the Mob to do a random hit on someone who works there.
              Vito will do it for $5k, the crackhead across the alley for
              1/10 that. Of course, then you owe them one.  -wiseguy
                \_ The crackhead will do it for a dimebag.  You overpay your
                   crackheads.  Way out of market range for crackhead hitmen.

8/16    Why does my Y! mail account always full of unfiltered spam
        mails (and they're obviously spams)? Why can't they do
        a better job like Google mail? Why does Y! mail charge
        for exporting email? Google mail doesn't do that.

8/12    Ugg, no spamd any longer?  I figured I'd have to just give up on my
        soda address (sad, very sad) but Vacation doesn't seem to be installed
        either, so I can't even leave a mesg. to people telling them where
        tom mail me now.  Or can I ?  Any advice out there.  Or can we get

7/17    Thanks to steven, et al. for restoring Soda. In lieu of www.csua providing
        status, could there be a text file with current status and future plans.
        I'm wondering if SpamAssassin is obsolete (and my procmailrc and scripts)
        and won't be restored, and what's filtering spam now.  thanks!

        on the emailer. I'm getting a bunch of binaries not found error

Finally, there's a section of more or less 10 tangentially related information. This includes some links to 11 introductory material about Unix mail handling which you might want to check out if you're new to Procmail and all this other stuff looks like Greek to you. Please 12 mail me about those so I can fix them, for the surfing pleasure of coming generations. I also try to include links to "competing" link collections. I do not wish to hijack information from other sites and thus I hope you will check out what these other collections have to offer. Please 14 mail me if you have links to other collections you think I should include. The list discussions are archived in part or in full at least at the following sites: + 25 Achim Bohnet's HyperMail archive is definitely the most popular. Probably it's also the most complete, going back to October 1995. If you are unable or unwilling to use the WWW archives, try to find a web-to-mail server (see the 28 "useful things by e-mail" links below) you can use. The Procmail-L listserv only stores a limited number of the most recent messages. Again, in the below listing, I have tried to avoid duplicating links which are already available from the Infinite Ink page. You can probably find some other useful sites by starting with this 49 canned Alta Vista search for "procmail". This merely attempts to strip out sites which have archives of the Procmail mailing list and/or otherwise a lot of Procmail material, on the theory that if you've looked around a little bit you will already have seen the stuff they can offer. What is left then is a very disparate collection of lone Procmail-related pages (presently, some 3,000 hits). This one is primarily useful if you've been reading the Procmail-L mailing list yourself and are looking for information you know is not in the archives. I managed to find a couple of the Rich and Famous pages and a few of the tutorials using variants of this. For the most part, these tutorials do not presuppose a lot of knowledge about Unix or mail handling on Unix. None of the material in the "howto" section is exactly rocket science, either -- let's just say it contains a lot less of this "pause now if your head hurts already" nonsense. But they all have their merits when it comes to presenting the issues, and none of the examples should be dangerous or anything. Probably worth a look even if you wonder about interfacing Procmail with some other Emacs mail mode. Procmail applications This section includes some good examples of more-complicated mail processing systems and library files. Many of these are systems you can install and use without delving into the details of how they work or even necessarily learning how to use Procmail on its own. Again, some of the 76 "Rich and Famous" pages below would fit in this category, too. Just install the whole package and use the parts you want; Included are a MIME attachment killer, an autoresponder which requires the correspondent to know a secret cookie before it will respond, parse different kinds of dates, and a lot more. It is a mailing list server (a la Listproc and Majordomo) written entirely in the form of Procmail scripts. You can find more information in the SmartList distribution. Hampton's 84 Spam Bouncer both bounces and auto-replies to unwanted mail (beta). Daniel Smith's 87 spamcheck recipes are available for anonymous ftp. You probably should have some prior exposure to Procmail because there is no real documentation (yet). On the receiving end, you have software to automatically add recipes from people you trust, with the option to add recipes from other people manually. Procmail utilities This section has links to programs which are not necessary for operating Procmail but which can be helpful in configuring Procmail, writing advanced scripts, diagnosing problems in your setup, and other associated chores. Marshall has implemented a 105 simple RBL lookup tool which allows you to use 106 Paul Vixie's RBL blacklist from within Procmail (example included). Procmail pages of the rich and famous As a rule, these pages contain both some sort of short introduction to Procmail and some example snippets from the authors' Procmail recipes. And of course, there's this 112 magazine article about Procmail. Sendmail and spam filtering are two obvious picks of topics, but if you have other relevant links you think would fit here, please don't hesitate to 118 mail me with them. Introductory material If everything else you read here is <insert favorite language you do not understand here> to you, the following might help. Net Abuse / Spam fighting resources Spam, or unsolicited bulk e-mail, is an ubiquitous problem on today's Internet and apparently one of the foremost reasons people get interested in using Procmail. There is hence a rather large assortment of spam-related Procmail pages. Other sections on this page contain spam-related material as well (notably the 123 spam-fighting section under Applications above), but the pages listed here are focused exclusively on net abuse topics. This should be rather easy to transform into a set of Procmail recipes. This assumes you have already set up Procmail and understand a bit of how it works. Also check out the self-contained 139 spam-fighting packages in the Applications section (above). Other assorted information Here are links to other topics which might be of interest to the broad Procmail-using public. If you are comfortable retreiving the FAQs by ftp instead, by all means use that and get them from your closest RTFM mirror. As for Africa and the Antarctic, I really don't know, but I'd guess users from those continents, too, had better try the US sites first.
