RE: Klez worm forging moderator's address?

Folks, this is built in to SmartList already. See here: http://www.hartzler.net/smartlist/SmartList-FAQ.html#Section_8.1 We use it, and it works fine, although it offers no protection against somebody sniffing your email between you and the SmartList server. -----Original Message----- From: Roger Burton West [mailto:roger@firedrake.org] Sent: Monday, April 29, 2002 10:37 AM To: smartlist(a)Lists.RWTH-Aachen.DE Subject: Re: Klez worm forging moderator's address?

Thank you, Roger, for your reply and suggestions. I went back 6 months in the archive, scanning subjects for password or related terms, but was unsuccessful. I wasn't able to find a search engine for the archives, either. FAQ 4.11 seems like it might be related, but would still have to be changed, since the whole "From:" header was forged successfully. Unfortunately, we use GroupWise here, which makes it impossible to change headers, only message bodies. Any solution I implement has to look into the body for the authorization, not the headers. I've finally decided to implement this recipe in rc.local.r00, at the end: # 29-Apr-2002-EKZ: Added recipe to filter out all submissions to list # NOT from ccp2.jhuccp.org. Done because of Klez worm forging From: addresses :0 * !^Received:.*ccp2\.jhuccp\.org /dev/null I think that this will filter out all message that don't have "ccp2.jhuccp.org" in one of the Received: headers. Thanks again for your help. -Kevin Zembower > Roger Burton West <roger(a)firedrake.org> 04/29/02 10:37AM >>> On Mon, Apr 29, 2002 at 10:30:39AM -0400, KEVIN ZEMBOWER wrote: >1.)

Keeping Mhonarc from archiving stuff not from accept
by Paul 'Baloo' Johnson 29 Apr '02

OK, occasionally the list address gets spammed. I get the message for approval, but the message goes to mhonarc and gets archived anyway. How do I fix this. -- Baloo

Strange subscribe behavior
by MPLS Resource Center 27 Apr '02

27 Apr '02

I use a form to allow folks to sign up for my mailing lists. One user is having trouble using the form and I think it might be a problem with smartlist. Whenever he sends a subscribe request, the following error is generated: X-Diagnostic: Mail coming from a daemon, ignored The domain of the address generating this problem is "@ib.sc.vu.lt" Could it be that smartlist doesn't know how to handle such a domain? Thanks, irwin

somewhat OT: email hosting service providers
by Richard G. Ball 26 Apr '02

26 Apr '02

I've been running a few smallish smartlist-based lists for about 7 years now but I have been told my current host may be ceasing operations and I'll need to find a new provider. I would like to continue using my personalized version of smartlist on the new host so I'd like to have login access along with procmail/smartlist support. Does anyone have suggestions for North American providers who can meet those needs?

RE: how to restrict postings from a particular email

Well, reject file worked fine for me. Thanks. Just curious, is there a way to restrict postings from a domain altogether ? What if sender keeps sending junk using different accounts from his domain.

Strange unsubscribe behavior
by Irwin Lazar 22 Apr '02

22 Apr '02

I had a strange occurrence this morning with one of my mailing lists. User2 unsubscribed, and the list removed User1, who is another list member from the same domain. The log file entry is below (names/domains changed to protect the innocent): X997 user1(a)domain.com 24689 user2(a)domain.com Removed: user1(a)domain.com You have been removed from the list..X unsubscribe: 997 user1(a)domain.com 24689 user2(a)domain.com by: user2(a)domain.com Fri Feb 15 09:31:56 EST 2002 Why would this happen? Thanks in advance, Irwin

We have found this feature useful for many reasons. Many list managers want to have something between allowing people to post whatever they want and unsubscribing them completely. For example, they may be posting lists of lightbulb jokes and chain letters, or they may be usually reasonable people who fly off the handle whenever a particular person or subject comes up, or they may be carrying on a temporary flamewar with one other person. While it may be reasonable to unsubscribe the offender, depending on the severity of the offense, some list managers prefer to leave them on the list but unable to post. I do not personally agree that a "simple" addition to rc.local.s00 makes more sense than using the reject file. There are several reasons, but one of the most compelling was that I found our list admins were already putting addresses of people they didn't want to post into the reject file, then reporting it as a bug when their posts were not rejected. They were showing me pretty clearly what the most user-friendly implementation of this feature would be. No one is required to make this change, of course, and I certainly do not expect Charlie's views to agree with mine. :-) But, since the subject of rejecting posts from individual subscribers, I am sharing the solution that we found to work to this problem.
