If you run Mathematica on any UNIX or Linux platform, could you let me
know the exact output you get from these 4 UNIX commands - they should
only take about 30 s to do all 4.

Change /usr/local/bin/math to where ever it is on your system.

echo "1+2" | /usr/local/bin/math
echo "1+2" | /usr/local/bin/math -batchinput -batchoutput
echo "1+2" | /usr/local/bin/math -batchinput -batchoutput | wc -l
echo "1+2" | /usr/local/bin/math -batchinput -batchoutput | sed '1d'

It would be better if you email me (the *return* address is valid),
rather than fill the newsgroup up. I already have information for
version 5.2 on Solaris (SPARC), but I am interested if other versions
and other platforms all give the same format of output (I am writing
something to parse this, so I need to know it will work with multiple
platforms and versions).


Data from SPARC.

sparrow / % echo "1+2" | /usr/local/bin/math
Mathematica 5.2 for Sun Solaris (UltraSPARC)

In[2]:=

" Cannot initialize Motif graphics "

sparrow / % echo "1+2" | /usr/local/bin/math -batchinput -batchoutput |
wc -l
4

sparrow / % echo "1+2" | /usr/local/bin/math -batchinput -batchoutput |
sed '1d'

Please note my email address changes periodically to avoid spam.
It is always of the form: month-year@domain. Hitting reply will work
for a couple of months only. Later set it manually.

The return address doesn't seem to be valid.

Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 9): 550

Sorry, it should be now. I'll drop you a private email anyway, but
thanks for making me aware of the problem.

I'd prefer to just publish my normal email address, but I tend to get so
much spam if I publish it on a newsgroup that I am not too keen on that.

For those who don't mind spending about $30/year you can subscribe to
SpamArrest and get rid of all the unwanted email. I've been using it for
several years and it works great. 99.99% of unwanted email is filtered out.
About 6 times a year some advertiser will go through the screening test but
I just put them on the block list. One should be able to give out a usable
email address and one can. Here's my email address. I don't worry about it
at all.

And what percentage of wanted emails are marked as spam? For software to
remove 99.99% of spam it must be very aggressive. Such software
usually dumps a large percentage of wanted emails too. Emails get scored
and depending on what score you accept as the break point, it is either
classed as spam or not.

Perhaps I have just been unlucky, but one of my university accounts,
which I'd have for 10 years or more, was getting 200 spam mails per day.
I eventually changed the user name, since it was just getting too much.

Now I get a lot less, and I do run spam filtering. But I think using an
email address for a short time is not a bad idea.

I sometimes wonder if the nature of email will have to change, but you
are obviously very happy about it.

The test is that the sender goes to a page where a word is displayed as a
stylized graphic and they must type the word back in. Machine generated spam
can't do this - at least not yet. Senders only have to do this once as they
are then placed on my senders list. I can remove people from the list, in
which case they would have to do it over again, or I can completely block
email addresses. And I can add people to the list myself. So the system
works very well. Most people who really want to communicate with me have no
trouble. Occasionaly, usually repliers from MathGroup, people don't bother
and it doesn't get through. I can also view all the recent unverified email
and retrieve some of this but I only do that every few days. So as far as
I'm concerned the system works very well.

It is very nice to have an email address that works and that people can use.
It is quite annoying when people expect me to retype or rearrange their
email every time I want to reply.

I used to use something very similar myself. I can't recall what it was,
but I think it was spam bouncer.

Funny thing was, a spammer got his spam blocked once, liked the idea and
said he had "accidentely spammed me" and would I tell him how what
software I used. I offered to do so for $10, but he never paid me the
$10, so the spammer never got told what it was.

I found some objected to that I must admit, but I can't recall the
reason I stopped using the software.

I take your point. I was unfortunate in this case that my DNS was set up
wrong, but usually my return address will work for a few months. If ever
I sign up for something now,

I'm sure we could go on about spam for ages, but this is probably not
the place. If you have access to the UNIX Mathematica, I'd appreciate
the output from the commands I gave.
