Spammers trying to abuse

[Vincent Diepeveen <diep at xs4all dot nl>]

hi,

I received clever spam - thought i'd warn you for it. They use gcc- 
help-help, obviously not the same as gcc-help, yet the confusion soon  
happens:

Hi! This is the ezmlm program. I'm managing the
gcc-help@gcc.gnu.org mailing list.


Messages to you from the gcc-help mailing list seem to
have been bouncing. I've attached a copy of the first bounce
message I received.

If this message bounces too, I will send you a probe. If the probe  
bounces,
I will remove your address from the gcc-help mailing list,
without further notice.


I've kept a list of which messages from the gcc-help mailing list have
bounced from your address.

Copies of these messages may be in the archive.
To retrieve a set of messages 123-145 (a maximum of 100 per request),
send an empty message to:
   <gcc-help-get.123_145@gcc.gnu.org>

To receive a subject and author list for the last 100 or so messages,
send an empty message to:
   <gcc-help-index@gcc.gnu.org>

Here are the message numbers:

   52126

--- Enclosed is a copy of the bounce message I received.

Hi. This is the qmail-send program at sourceware.org.
I'm afraid I wasn't able to deliver your message to the following  
addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<diep@xs4all.nl>:
194.109.24.138 failed after I sent the message.
