    Re: Missing messages (for Dan Hogan, etc.)

    I checked my IPS -Sympatico and found that there is a spam folder that
    is flushed every two days. These messages are not delivered to my
    Outlook folder when I do a get mail. The daily could in this folder is
    200 a day. My outlook also further filters and it catches about 2 day.
    I do not have time to review the 200 messages that sympatico "caught".
    But I too feel that sometimes important messages are caught as spam.
    Don't know what to do about it. I receive about 10 good messages  a day
    at home out of a possible 210 that are addressed to me. If others are
    getting the same then there is a lot of bandwidth taken up with waste!
    What can we do. Nothing that I can see.
    We will have to learn what words are used to trap mail and steer away
    from them.

    Subject: Missing messages (for Dan Hogan, etc.)
    This is nothing to do with navigation, but is relevant to the Nav-L
    There seems to be a problem of certain Nav-L messages not arriving at
    intended recipients, which is getting worse. It is certainly affecting
    my input, and from what I hear is also affecting several others. It may
    well be related to spam filtering.
    Some years ago, getting overwhelmed by the rising tide of spam, I needed
    to do something about it. I was aware that some kind organisation had
    taken to marking suspected spam with a warning in the header of the
    message. After a long period of checking I felt safe in assuming that
    all the messages so marked really were spam, and no genuine, wanted,
    messages were ever marked that way. So I set up a filter, as my ISP
    allowed, to discard such messages before they were ever sent to my
    mailbox. A few spam messages still got through, but most were removed,
    and that system seems to have worked reasonably well for some years. I
    was unaware of any genuine messages being filtered out. Perhaps many
    Nav-L subscribers do something similar.
    Over the last few weeks, however, I have become aware of many Nav-L
    messages failing to arrive. Another Nav-L member tells me that he has
    discovered certain Nav-L mailings had actually been marked as suspected
    spam. Something appears to have changed for the worse. Either something
    has changed in the messages or their headers as sent out from Nav-L,
    which causes some, but not all, to be marked as spam. Or perhaps the
    anti-spam algorithm has changed in such a way that it's now marking
    genuine messages as spam, where it shouldn't. Neither of these are under
    my control.
    How can we deal with this? First, is it really a genuine problem,
    affecting many Nav-L members?
    Second, am I right in diagnosing it as a spam-filter problem?
    Second, can we at least be sure when we are missing messages? Would it
    be possible for Nav-L to attach a serial number to each message,
    incrementing by 1? Could this be appended to the "subject" line,
    perhaps? Or even automatically inserted as the first line in the text?
    Then, we could be quite sure about what's being missed. I am no expert
    on such matters, so have no idea whether such a suggestion would be
    impossible to implement, or trivially easy.
    One approach may be for me to ignore Nav-L incoming emails altogether,
    and instead go to the website archive. Would that fix the problem?
    It seems that those damned spammers are destroying the usefulness of
    emails. Must they win?
