Spam, CCL, and me...

The question from subscriber prompted this message to all subscribers.
 1) I do understand subscribers concerns that they do not want to post to
    CCL from their company/university e-mail address. Yes, there are policies,
    and liabilities involved. Yes, it is much safer to post from you
    PRIVATE email address. However, there is an advantage to post from
    company/university address.
 2) The reason for posting with the company/university address is that
    I very reluctantly put them onto a blacklist. That is, you can post from
    these addresses and your mail will not have "Access denied" bounce.
    The private accounts like on yahoo.com or hotmail.com, etc., often
    have problems posting to CCL since the respective domains are on
    the blacklist (since I get tons of spam from them).
 3) You can post to CCL from ANY address on Earth, assuming that the subnet
    from which you post is not blacklisted. If it is blacklisted (i.e.,
    mail bounces with 'Access denied' from chemistry$at$ccl.net), you need
    to send your message to me: jkl$at$ccl.net so I resend it. The subscription
    list is not checked when deciding if message can be posted. Your
    subscription address is only the address WHERE YOU GET MAIL from CCL.
    You do not have to use it to POST to CCL. So you can still receive mail to
    your company address, but post to CCL from your private address, or your
    friend's private address, whatever it it.
 4) As I said, many "free e-mail accounts" will have problem posting,
 since
    the providers of such service also provide a opportunity for spammers.
    Now, if your mail from the private address bounces from CCL, send it to
    jkl$at$ccl.net (I do not have a blacklist attached to this address, to my
    demise and despair) and  I will resend message to CCL for you.
 5) Read the bottom of the messages you receive from CCL. For example,
    when you post to CCL, put the four letter word, CCL:, somewhere on
    the Subject line. It will prevent your message to go to unconditional
    manual review (it may well still end up there if you use some words which
    are often found in spam messages or some other things in your message may
    be "suspisious" to the CCL scripts).
 Please understand that CCL gets about 1000 spam messages a day.
 You see only one in a month or less, on average, but it happens because
 I work on the principle 'better safe than sorry'. Of course,
 once you have to screen mail manually or automatically, it will
 cause delays and often human errors. Oh well... There are people out
 there who screwed it up for all of us... We need a new e-mail standard
 which authenticates the sender of mail. I will gladly receive all my
 spam, if they pay me a $1 per each message. I would be a millionaire by now...
