Majordomo-Users (July 2008) |
I agree that the subscribers are not the ones sending the graphical messages if graphical messages are what is causing the problem. Actually, I think that it may be all messages from spammers, whether graphical or otherwise. I didn't save any of the bounces I was getting back, but I think that the times on at least some of them did correspond to times of some of the blank messages. Those messages were not all graphical, because they did have text that caused majordomo to respond. The thing is messages, apparently from spammers, are coming in, and apparently, are causing majordomo to create blank messages in the digest temporary directory. The messages are NOT going out to the regular list members - they never were. I do have my lists set up so that only list members can post. The blank messages have never gone out through the regular messages. They only show up in the digest temporary directory, and if left alone, appear as blank messages within the digest. I am running demime, and DrWeb to filter messages on the site.The digests last night did run without any problem. We modified line #176 as Daniel Liston suggested, and that, along with removing all zero content messages with a script as part of the cron job to create the digests, resulted in normal digests. I am still left with these blank messages being created in the digest temporary directory, but the problem is now at least manageable. Probably I will now create a new list starting with an alpha character lower than the two active lists, and see if I can dump any blank messages into that new list's directory to further ensure that blank messages don't get out to any digest subscribers. Right now, these blank messages are only going into one of the two active list digests directories, and it is the one with the starting with alpha "s" as opposed to alpha "v". -Tom----- Original Message ----- From: "Peter P.

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 ---- Peter P. Benac, CCNA Emacolet Networking Services, Inc Web and Mail Hosting.

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 _________________----- Original Message ----- From: "Ed Kasky" <ed @ esson . net> To: "Daniel Liston" <dliston @ sonny . org>; <majordomo-users @ greatcircle . com> Sent: Saturday, July 12, 2008 1:03 AM Subject: Re: Majordomo and spammers FYI, demime also strips attachments at the same time that it strips the mime from a message. I have lots of subscribers scratching their heads on that one... Ed Follow-Ups:
