    You don't say what OS you're using. If it's Windows, you could give
    MailWasher a try. It's an 'inbox inspector' that allows you to view what's
    in your pop3 mailbox before downloading the entire content. Very good.

    http://www.mailwasher.net/

    If you're using Linux, then IMHO, SpamAssassin is the best way to combat
    spam that I've seen.

    http://au2.spamassassin.org/index.html

    The mail server I use has SpamAssassin built in, and is superb.

    Seconded. I use this very combination and K9 alone has a 99.3% efficiency
    since august (last I reset statistics). Coupled with SpamPal the efficiency
    is about 100%.

    I've set a rule in my mail client to delete all mails that have been
    categorized as spam by both programs, while moving those that only one of
    them have pegged into a spam folder for later checking. I get maybe 2-5 in
    the spam folder a day, and dozens a day deleted instantly, and never any in
    my actual inbox.

    Yeah, I'd like to see Doc explain how anti-virus software qualifies as
    anti-spam software.

    COTSE has absolutely the BEST e-mail filters on the planet. You really
    can't get more control over your e-mail anywhere else. In the year+ I've
    had my account there, I have yet to receive even one piece of spam other
    than those I've manually injected to train one of the filters.

    Btw, I should explain something... when people ask for anti-spam tools, I
    start by pointing towards anti-virus because, oftentimes, anti-spam tools
    go best with anti-virus tools. After all, don't most viruses/trojans arrive
    through e-mail, just like spam?

    Well, that is a bit of an exaggeration....


    I run Linux here, and wrote my own spam killing program, which you can
    find at http://tinyurl.com/3c3ag.

    It's just a bunch of scripts with procmail at its heart, but I get no
    spam at all and *I* am in control of my mail, no one else.

    No one has any problem at all getting through to me IF they use their actual
    return address, read that mail box, and are not sending bulk mail without
    asking me first.

    Here's how it works:

    -----------------------------------------------------------------------------

    pass-list ---------> block-list (content-filter) ---------> Challenge-Response

    Along with many others, I use a filter designed like the above:

    I never see any spam.

    I send out very few C-Rs.

    I don't have to mess with my filter at all.

    Spam is just gone from my life, no muss and no fuss.

    The only complaint I have ever had was from a domain that turned
    out to be on the dnsbl (dns blacklist) for spamming.

    Anyone can reach me with no muss or fuss if they use their real return
    address.

    (In some ways, Challenge-Responses are like Caller-ID for phones: Someone
    who wants to communicate with you must use their real return address, and
    actually read the mail there.)

    On the rare occassion that I send a C-R to an innocent party (I have to
    assume that his has happenned at least once.) whose address has been forged,
    then I have done them the favor of letting them know that it is being forged,
    which can cause a person one hell of a lot of trouble.

    They have my real address and are told in the C-R that I have a copy
    of the headers of the post if they need it.


    Like I said: ONE complaint, ever, and from spammers.

    C-Rs are only one stage, and the final stage, of an effective mail filter
    that is designed like so:


    PASSLIST

    Where every friend, associate, commercial mailing list, discussion
    mailing list, business, and non-profit org is given free access
    to my inbox with my consent.

    Anyone you send mail to must be passlisted.

    This is where you make SURE you get all the mail you REALLY need
    to get, or just want.


    BLOCKLIST (Content-Filter)

    General, to kill most of the spam. You can use SpamAssasin here
    called by procmail. Or just use good procmail recipes.

    And specific, where domains and addresses are killed for various
    offenses, generally repeated C-Rs that aren't returned.

    (Do remember to blocklist your own address, or some clown will
    send mail to you with your own address on the From: line and
    set up a mail loop.)

    You just can't catch all the spam with a content-filter like
    SpamAssassin. If you even try, you will end up losing mail
    that isn't spam, and getting some spam anyway. And you have
    to update your filters all the time to keep abreast of the
    spammers.

    (As well as save the spam to look through to make sure there
    isn't any mail you want in there, which rather defeats the
    whole purpose of a spam filter, in my opinion. I don't want
    to ever see that garbage.)

    Better to just kill the mail you KNOW is spam, and send a
    C-R to the few that your content filter isn't sure about.

    CHALLENGE-RESPONSE

    A little note that asks the receiver to paste a password on the
    Subject: line and return it.

    The Subject line on the C-R should have Re: original subject
    on it.

    This forces people to use their actual email address if they want
    me to see their posts.

    (And to read their mail...)

    This is only required once. From then on, it's as if there is no
    filter on my mail from their perspective.
