Thanks.
Here is a general overview of how I am set up.
I have sendmail configured to send outgoing mail to my DSL provider.
The mail server I use is called smtpout.bellatlantic.net.
I have 4 different POP3 mail accounts that I check with fetchmail.
One of them is my account with BA. The other three are with my ISP who
hosts my david-steuber.com domain. I pick up mail that is addressed
to david-steuber.com from a server called email.steuber.com.
I use a typical setup in ~/.fetchmailrc to poll the POP3 servers. For
all four accounts, the rule is that the mail in the POP3 account goes
to `david' here.
The headers make me believe that fetchmail is bouncing messages using
FETCHMAIL-DEAMON.david-steuber.com in the From header. I am not using
procmail or any other filters that I am aware of. AFAIK, all the mail
should end up in /var/spool/mail/david and _not_ be forwarded
elsewhere. Clearly it is. As the mail is from my domain, the rule in
sendmail.cf is not going to recognize the bogosity of the from
address.
I am assuming fetchmail is the culprit because of the headers. I
suppose it could be sendmail, but then why would
FETCHMAIL-DAEMON.david-steuber.com appear in the From header?
Normally, I have no problem with SMTP rfc-822 headers. But this is an
exceptional case. The Received headers are not in the normal order of
relayed mail. The spamfilter that BA uses (I'm assuming it is them)
to bounce back the mail that fetchmail apparantly forwards does not
include the body of the message. Heck, the mail I get is such a
complete mess that I couldn't figure out what was going on. That is
why I decided to post, in the hopes that someone more familiar with
fetchmail could tell me what is up.
Perhaps I should put some entries in /etc/aliases, but I am not at all
sure that would help. I normaly get the mail sent to my accounts,
including the trashcan account.
I also find it odd that the spamfilter that BA uses bounces the mail
to email.steuber.com instead of mailn.bellatlantic.net. I should be
picking up the bounces from a different account. Perhaps this is a BA
issue. Or perhaps it is because BA sees the From header as being from
the david-steuber.com domain and that is why it sends the mail there.
All this tells me that fetchmail is the problem. If fetchmail is not
the problem, then I am extremely confused. I've used fetchmail for
several revisions now without changing my ~/.fetchmailrc file.
Perhaps there is some new control word I need to add or something?
# Configuration created Thu Dec 17 19:29:08 1998 by fetchmailconf
set logfile "/home/david/.fetchmail.log"
set postmaster "david"
poll email.steuber.com with proto POP3 and options no dns timeout 30
user "user" there with password "password" is david here
options no rewrite
There are no clues in the _huge_ file ~/.fetchmail.log. I've just
truncated it to see if I get an indication the next time this
happens. All I saw in the file were the normal connects. Nothing
about forwarding the mail.

' OK, obviously you're using Fetchmail to retrieve your e-mail, so this
' bit is basically just saying that Fetchmail has sent you this message.
Yes. For incoming mail, this is the normal head of the message.
Obviously, the From header is dependant on the sender. In this case,
BA is sending the mail.

' Some system, somewhere along the line has tried to send e-mail to
' [EMAIL PROTECTED], which is invalid. From later entries, I
' suspect this was a spam filter called in conjunction with Fetchmail, but
' I'm not positive of this.
My belief is that fetchmail tried to send the message. It is supposed
to drop off mail in my local mailbox. Fetchmail does use sendmail to
do this so that it doesn't have to muck about with the spool file.
I'm not running any spam filters at my end.

' It looks like your local system's Sendmail is configured to relay
' through Bell Atlantic's e-mail system. This is perfectly legitimate and
' has certain advantages, but it can also produce some pretty convoluted
' chains of error messages, as you've displayed here.
I have to do this because some ISPs will not accept mail from any host
that does not have a DNS MX record. Primenet is an example. They do
this so that dialups can't spam user's accounts. Mail goes into my
mailq and is relayed to smtpout.bellatlantic.net. Clearly, the host
has more than one name, or is on a round robin DNS or something.

' OK. [EMAIL PROTECTED] has tried to send e-mail to
' [EMAIL PROTECTED] Clearly this is bogus.
Yes. My question is why is FETCHMAIL-DAEMON doing this? I have no
such user, so I am assuming that fetchmail uses this name.

' Here's the reason for [EMAIL PROTECTED] rejecting the
' mail. (I think.) I'm a bit foggy on Fetchmail's interactions with spam
' filters, so I don't know how you might have this configured. It's also
' conceivable that some other system rejected the mail and it got bounced
' back to Fetchmail.
I have no filters installed. I don't know if fetchmail has decided to
include its own filtering facility. That would be rather un-unix like
of it. Since the mail was sent with a bogus To: address, the RCPT
command is bound to fail.

' This last line is presumably the cause of all the trouble. Something
' (presumably the spam filter) picked up on the Sender address, which is
' bogus, rather than the valid From address, and tried to bounce the mail
' back to the sender. (Note that the From address could as easily be
' bogus.) You may want to look into your spam filter's configuration and
' options. Some spam filters do quite nicely when used in conjunction
' with SMTP, but end up producing problems when used in conjunction with
' POP and Fetchmail.
The reason I don't use a filter is because I want to save my spam for
the day I get to cause horrible vengeance on said spammers by
publishing all their mail on my website.
Then again, I could just delete it.
This mail was not from a spammer, but from someone useing a forged
address to respond to a usenet post I made. I am guessing that this
is the case, because I saw a response from the same person in the
group. My general rule of thumb is to look in the groups for
responses and to respond only in the groups. I do occasionally use
e-mail as a curtesy.

Linux allows 32 groups. You'll have to edit a couple of header files and rebuild
a whole lot of software to increase it.
You could try NIS netgroups instead.

Educate me. What can you DO with BeOS? My understanding is that BeOS's app
support is pretty meager. Specifically, what freeware exists for BeOS?

I see the same, or something similar. For me, 1.3 will not launch into
interactive mode, but only in web mode. And it is logging nothing.
Either it is broken with our configurations, or has changed so much that
I am missing something completely. Using 1.1 ATM.

It's a mediaOS yet has no support for Sorenson, DVD Video or DivX.

Personally, I would have loved to have traded it just for
AmiPro or WordPro. However, the user culture on Windows
isn't very tolerant of that sort of activity.
Why use a platform that "runs everything" when you can't
infact just run anything?

FWIW, vim (a vi clone) is better, especially in that it has built in
help capability. Learning vi is VERY painful.
But vim may not be installed on all variants of unix, so using special
stuff in vim may not be the best approach if you must work on many
systems.
It is good to have as a help reference though.
Tradeoffs, tradeoffs. :-)

That's not a "problem" and should be left alone.
It's a security feature.
If you want to run a file that's not in your path, but is in your current
directory ./file is a good habit to get into.
