Hi there,

since we are currently witnessing a *heated* debate into which direction
this list should be going (hello, Ed...), I'd like to draw your attention
to something that is being brought up at least once a week: forging one's
own mail address to "fight spam". Now, I do it to, but according to what
Justin Sheehy has imvho quite gracefully put in his posting to c.e.g.

My suggestion would be to cancel all messages that have illegal
headers. If this list is to discuss "serious" matters, one should
expect the writers to know what they're doing, i.e. to have read
their RFCs.

In the same vein, I think that messages from [email-masked] ought to be
cancelled. I for one haven't seen anything senseful coming from either 
side, yet.

Now hate me }:->

Cheers,
Robin

I have included the relevant secyions of RFC 1036 below.
By real address, I am thinking of a working electronic mail address
that will reach the poster.

Incorrect.

It requires that your header contains "the electronic mailing address
of the person who sent the message".  I read this as "a correct,
functioning address that will reach the person who sent the message".
If an RFC states that you need to provide something, it should not
also have to specify that the something in question actually work.

That is an acceptable solution to me, although actually scanning that
mailbox before mass-deleting might be a good idea.

***
RFC 1036              Standard for USENET Messages         December 1987

2.1.1.  From

    The "From" line contains the electronic mailing address of the
    person who sent the message, in the Internet syntax.  It may
    optionally also contain the full name of the person, in parentheses,
    after the electronic address.  The electronic address is the same as
    the entity responsible for originating the message, unless the
    "Sender" header is present, in which case the "From" header might
    not be verified.

2.2.2.  Sender

    This field is present only if the submitter manually enters a "From"
    line.  It is intended to record the entity responsible for
    submitting the message to the network.  It should be verified by the
    software at the submitting host.

***

Thus, if neither of those headers contains your email address, then
you or your software is not compliant with the most important RFC for
usenet messages.

I do not wish to aid people in acting in a way that is clearly
incorrect and inconsiderate.  I am not trying to stop them, but
neither will I aid them in their futile movements.

Hi Robin....

I agree with both suggestions.

Hope your Siberian and your Cherry are doing much better.  :-)

First, type ctrl-R to reveal "Rich Headers".  Then you should see the
Bcc: line.
