    Hello:

    Not too sharp with this stuff.

    re Spam.

    a. I see that a lot of the e-mail spam I get does not have my true e-mail
    address on it.
    Has the @comcast.net O.K., but not my real prefix.
    How does it make it, therefore, to me ?

    b. Anyone using the Comcast spam blocker ?
    Work well, etc. ?

    c. Would like to find a free, or inexpensive, blocker.
    Can anyone suggest any good, and hopefully, simple ones, please ?

    d. If possible, would like to be able to denote what is to be blocked,
    rather than all the ones I do want to get thru.
    Is this possible, or do the idiots who do this continually change their From
    addresses ?

    Thanks,
    Bob

    So why are you making off-topic posts, Robert11?

    Illogical, given that it refers to your excuse.

    Exactly!

    > How does it make it, therefore, to me?


    Classic erroneous presupposition by someone who is ambivalent, Robert11.

    > b.


    Classic disregard for netiquette, as evidenced by your ongoing replies.

    > Anyone using the Comcast spam blocker?


    Classic hallucination.

    Classic insecurity complex, as evidenced by your need to drum up support.

    > c.


    That's your problem.

    When, allegedly?

    Since you asked so nicely...

    What do you desire most?

    Not me...

    It might help if you post your /real/ email address here. Some high-
    educated guys in this group could help you. I mean, how can we help if
    you post with an email address like "",eh?

    The headers are NOT used to route e-mail. The commands that the e-mail
    client sends to the SMTP server are used to determine who gets a copy of
    the e-mail. Although users tend to separate the headers from the body,
    those are just different portions of the same message (i.e., the top
    portion seperated by a blank line from the bottom portion). Mail
    servers can prepend onto the headers (i.e., add to the message). Where
    the message gets sent depends on the RCPT-TO command the e-mail client
    sends to the SMTP server, and that information is never contained within
    the message. All the headers and the body of the message are contained
    within the DATA command the e-mail client uses to send the content of
    the message; i.e., it is all data which means the e-mail client can put
    anything it wants in the headers, since that is data, too, and then send
    it anywhere independently of those headers according to the recipient(s)
    listed in the RCPT-TO command. If you want to know more, read RFC 2821,
    Simple Mail Transfer Protocol (SMTP).

    I do. Leave it enabled. It will put spam into the Screened Mail
    folder. Although they recommend that you occasionally use their webmail
    interface to check this folder in your mailbox, I don't bother. Their
    filter has to been "loose" to avoid or reduce false positives (to
    eliminate complaints from their customers) and why some spam still leaks
    past.

    SpamPal (www.spampal.org). Completely free (not adware, bannerware,
    crippleware, demoware, or any of that crapware), although the author
    will accept optional donations. It primarily detects spam using DNSBLs
    (DNS blacklists) of known spam sources but each blacklist behaves
    differently so you need to decide which ones to use. SPEWS does not
    identify spammers but instead rates the trustworthiness (or spamminess)
    of ISPs and e-mail providers, so they cut across a large swath of IP
    addresses, if not all of them, for an ISP or e-mail service. They don't
    identify spammers but instead identify spam-friendly or spam-lazy
    providers and rely on coercion to get the non-spamming victims at those
    domains to bitch to their provider to get rid of the spammers there. I
    use SpamHaus SBL+XBL, ORDB, SpamCop, NJABL, and SORBS along with several
    plugins that add other methods of detecting spam than using blacklists.
    The Bayesian plug-in detects spam based on word weighting in a database
    and is affected by your history of e-mails (so it helps to have a set of
    good and bad e-mails to pre-train the filter; otherwise, it can be
    several days or a couple weeks before it gets enough e-mails to learn
    which ones are spam and which are okay). SpamPal's Bayesian filter can
    also learn from SpamPal and the other plug-ins. The MXblocking plug-in
    eliminates spam that originates from infected PCs running trojan mailers
    (because they have dynamic IP addresses because they are dial-up or
    cable/DSL users). The RegEX plug-in gives you regular expressions that
    go far beyond what you could define for rules in your e-mail client. I
    haven't needed to use the RegEX plug-in because SpamPal and the other
    plug-ins work superbly. The HTML-modify plug-in not only detects HTML
    spammy mails but can neuter them (although it may duplicate some
    features already available in your e-mail client).

    SpamPal runs as a proxy. Previously you had to reconfigure your e-mail
    client's accounts to go through the proxy but they have a wizard now to
    do that (but I prefer editing the account properties myself). SpamPal
    works with any POP3/SMTP compliant e-mail program. However, it does not
    support SSL which, for example, is required by Gmail and some ISPs also
    provide secured login ports for their SMTP and POP3 servers. SSL
    connects only secure your login credentials (username and password) and
    NOT the content of your inbound and outbound messages. You'll need to
    use encryption within your e-mail client to secure the content of your
    messages. You can use sTunnel to provide SSL login connects for SpamPal
    (or SSL for other applications) but it isn't easy to setup (well, ease
    depends on your expertise).

    Filtering on the From header is worthless. Spammers always change that
    value and it is bogus or points at someone else. That's why users
    sometimes ask how big the blocked senders list can get because they have
    been fruitless attempting to block spam on an ever-changing header
    value.

    SpamPal has a whitelist where you can specify recipients that you always
    want to receive their e-mails. There is also the trick of adding a
    passcode or magic string to the Subject or to your name (in the To/Cc
    headers) which a rule will allow to pass or keep in the Inbox. SpamPal
    tags which e-mails are spam and it is up to you by defining rules in
    your e-mail client to decide what to do with them. So, besides the
    whitelisting in SpamPal, you could define a rule that keeps e-mails from
    known senders in your Inbox (or move them to a "trusted" folder).
    Outlook can define a rule based on an entire contact folder (i.e.,
    address book) of known senders but Outlook Express doesn't so you end up
    having to create a rule which is effectively a whitelist that you could
    just as easily put in SpamPal. Nope, unfortunately SpamPal doesn't have
    an address book import feature, but you could export your contacts and
    edit that list so it can be used as a whitelist by SpamPal.

    There are other anti-spam products available. SpamPal is free and
    supported by its author and has a help forum for the community.
    SpamBayes operates as a plug-in to Outlook (so it is only functional
    within Outlook) and only provides Bayesian filtering; however, I believe
    it can be ran as a local proxy similar to SpamPal to alllow its use by
    other POP3/SMTP e-mail clients. Mailwasher is another choice (but NEVER
    enable its bounceback function) which also uses blacklists. It used to
    be free but I haven't checked in awhile, plus they never route any
    donations to the blacklists (which are free) to support the service on
    which they rely for their *commercial* product (they don't participate
    but instead are just greedy).

    A better group to ask about getting rid of spam is alt.spam. Or ask in
    a group related to whatever e-mail client you use.

    That To header you see isn't what mail is actually routed by.

    Others will offer you various blockers; I'll add "or just do it yourself
    with filters you create for your mail client.)

    In most cases the From address isn't actually the spammer's anyway.
