Re: Majordomo and spammers

Tom,

   It is not your subscribers that are sending the graphical messages. It is
the spammers.  

   I would be more curious about what type of spam catching software you are
running on the front end of all of this.  My mail server is running
SpamAssassin, and Mimedefang. Plus I have the list set so only list members
can post. Rejects never end up archived or digested. The mail server checks
for RBDNS, DKIM and SPF records as well.  

   Very little Spam makes it to any list I host and 99% if that is rejected
because it comes from non-members. If that much spam is making to a backend
mail processor you might want to beef up the front end.   

Regards,
Pete

Sorry All,

I responded to earlier messages from Daniel Liston, and did so without 
copying in the list, as I just hit the reply to button.  Following is my 
response to the first message:

Thanks Dan,

Maybe you are correct in the graphical nature of the problem, but I doubt
it.

I have two lists with about 700-750 mostly long time members.  They know
that majordomo strips off any image files, and should not be submitting any.
If they did, it would only be an occasional image - right now, I am getting
a lot of these zero files.  Prior to installing Joe's patch, I was able to
tie the date and time of these blank files to the time that majordomo was
bouncing messages back to the spammers.  Also, I did not have this problem
on my old server which also used demime.  The problem started when I moved
to a new server.

I have already looked to see what files are queued up for the digests, and
there are zero content files sitting there, and arriving regularly.  The
sequence problem I was running into seems to have ocurred as a result of
deleting these zero files.  The solution now appears to be in renaming and
renumbering these files so that they start with 001.  When I did that
earlier today, I was able to pick them up in digests.

I now have a script which will be tried with the cron job tonight.  It will
delete all zero content files, and then rename and renumber the remaining
files immediately prior to calling the cron job to create the digest.  If it
works, the problem will be solved.

I have no idea what is different now than with the earlier server, except
for the mail program.   Whatever, I will keep you posted on the outcome.

-Tom
