1, 2 and 3 letter logins are easy to mass-email. Does the account
fall into this list?

I have received spam sent to keesan at a number of ISPs, some of them not very
well known. I think they just take logins and combine them with ISP names
and send spam out that way.
Shadow.net knows what the problem is. Yesterday they improved their spam
filter to reject headers of a certain format. They have had complaints from
a few other people who tried to mail their customers from shell accounts, and
they will fix the problem pronto. The phone was answered immediately (no
menu, no wait) by a really knowledgeable support person who spoke perfect
English with a Spanish accent and who diagnosed the problem at once. It is
nice to know some ISPs are competent (unlike AOL, Earthlink....). I recommend
them to anyone living in South Florida.
Webmail might be a good temporary solution to grexers who cannot send mail
to places with this sort of spam filter.

The account in question has its ID formed by a common 7-character first name
followed by a 1-character last name (e.g. robertoa). So I guess it's possible
the spammer just got lucky when constructing a target account name. But I'm
still wondering if the information could have come from grex...

It could have. The person would have to be a user first. But it's more
likely it was just random coincidence.

OK, so let's say the user *was* a grex user - how does that help him find out
info about other user accounts which are inconspicuous due to lack of
participation? If you don't wish to say because this will encourage other
spammers, I'll understand...

The password file can be read by anyone on grex:
} Respond, pass, forget, quit, or ? for more options? !ls -lFg /etc/passwd
} -rw-r--r-- 1 root wheel 2075714 Oct 29 13:29 /etc/passwd
It is kinda big, but there it is.

OK, yes, that's the standard way one would get the user list.

Today's high load average was due to a chain of logins created from one
particular place. This appears to be some sort of file sharing scheme -
I'm not sure of the exact mechanism (which in any case probably invovles
client-side software which we don't have) - but the usual result is the
account gets disabled due to "high ftp volume", which then results in a
high cpu load as the client-side software is apparently too stupid to
give up on a login failure, but just tries again, over and over and
over...

Re 80, 81, 85, 87, 88, and maybe more:
I'm recently seeing email to Grex hanging in a mail queue with the message
"Deferred: Connection timed out with grex.cyberspace.org.". It appears
that almost every message I send to accounts on Grex times out and retries
at least once or twice. I'm pretty sure this didn't used to happen. I have
to suspect that something in the way Grex handles mail, probably relating to
the reverse lookup, has changed to make this vastly slower (on the order of
a minute or two). When the queue starts processing the message, it's at least
that long before it times out again.

I have yelled at STeve for not replying to email and been told that he did
reply then have it show up several hours later. Time stamps show that he did
send it when he said he did. Yesterday he sent a reply at 14:00, it arrived
here around 19:00, another was sent around 17:30 to arrive around 20:50. I
have been talking to contractors via email and was wondering about one of them
being interested in the job since he didn't respond. Time stamps show that
it arrived here about 36 hrs after he sent it.

Nothing has changed on grex recently that would affect any of this. If
there is a high load average on grex, grex will temporarily stop
receiving mail - it's been doing this at least since we were on the
sun-3. A timeout of a minute or so for the reverse lookup probably
means something is up with somebody's DNS server - if this is important
to you, you might want to figure out which IP address and DNS server is
being slow. "slow" behavior can be hard to recognize due to name
caching, so there are a lot of sloppy system administrators out there.
I don't know enough about the path STeve's mail takes to reach Glenda to
speculate why it might be slow.

Right; look at the "Received:" lines, comparing timestamps, to see where it
got delayed.

I'm getting a lot of mailing list messages twice, or out of order, lately.
I also had someone complain mail they were trying to send me bounced the
first time they tried, because Grex wasn't responding. I'd guess it's
probably the unusually high load averages lately doing it.

Mail to mcnally@umich.edu forwards to grex and to an archival mailbox
on a webmail service that I don't often check. Lately I find that
messages frequently show up in this other mailbox a full day before
they arrive in my Grex mailbox. Something is going on with our mail
reception that wasn't happening before.

I have also noticed large delays in receiving e-mail; sometimes
my inbox almost looks shuffled, as time of arrival has little
relationship to time sent. Some days I get very little e-mail,
and then later I get a flood of things sent during the dry spell.
It looks like Grex needs to do something about mail priority.

I would like to thank whoever fixed several problems with lynx: it no longer
loads pages 2-5 times, r works to remove lines in the bookmarks file, and I
can set options and save to disk.

I have polytarp on my don't write-tel-chat-talk list in .login (I just
checked) but keep getting talk requests anyway. What might I have done wrong
in setting this up? I used the change program.
