User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)
Build Identifier: 

The mail being sent to mozilla.org to request being removed from a news group 
was rejected/returned to me with a permission error, asking me to check with my 
administrator.

Reproducible: Didn't try

Steps to Reproduce:
1. Loaded mozilla.org and found the newsgroups
2. clicked on unsub link next to the webtools newsgroup
3. a new email from outlook popped up with the to address as mozilla-webtools-
[e-mail] and the subject prefilled with the word unsubscribe
4. I sent the email w/o filling in the body of the message


Actual Results:  
I received notification that my request was denied and to check with my 
administrator.  I emailed my administrator and he told me that was not rejected 
on our end, but on mozilla's.

Here is the content of the mail that was returned:
     To: [e-mail]
     Subject: unsubscribe
     Sent: Tue, 6 Jan 2004 14:38:52 -0800

     did not reach the following recipient(s):

     [e-mail] on Tue, 6 Jan 2004 11:35:30 -0800

          66.124.249.25 rejected by DCC>

There was an attached dat file that read:
    Reporting-MTA: dns; sf-dc-msg-01.hq.paymap.com

    Final-Recipient: RFC822; [e-mail]
    Action: failed
    Status: 5.7.1

    X-Display-Name: [e-mail]


Expected Results:  
Perhaps sent me a confirmation that I successfully unsubscribed?  I'm not sure 
what the expectations are, but I can tell you I'm still receiving mail, so the 
attempt at unsubbing didn't work.

DCC is a content-based spam filter.  Since you left the body completely blank,
I'm guessing it matched some content-less spam.  You can try resending it with
something (anything) in the body of the message.  It doesn't really care what's
in the body, since it uses the subject line for the subscribe/unsubscribe.

The bounce message you attached appears to be claiming that mailgate.paymap.com
is the server that bounced the message though, not mail.mozilla.org.  We do use
DCC though, and that bounce message is not exactly formatted in a standard way
(it's missing the Remote-MTA line in the .dat file, which would tell you for
sure the name of the server that actually did the rejecting).

Dave, I sent a message that had text in the message, just the word Unsubscribe, 
and you were correct that that is why it was rejected.  This time I got 
information back that said I needed a password and an email address.  So it 
does care what was in the content, because it responded specifically to what 
was there.

I included the MTA line (the whole dat file for that matter) in the write up of 
the defect.  It reports that the block was on my side, but according to my 
admin, he says different.  And the proof is in that I was able to send to the 
same address today, the only difference is that there was text in the body of 
the message.  So the MTA line isn't entirely truthful.

This should be fixed permanently now (if the problem was actually on our end).

We killed off DCC the other day because it has way too many false-positives.
