I administer email@example.com, also known as firstname.lastname@example.org The newsgroup is unmoderated, but the list is moderated. Email from list members gets right through without moderation. The intent is that I hope to catch the occasional legitimate on-topic message that comes from a non-member address, and allow it to pass. But all the spam should be discarded. I don't even want to be asked to review it. I have setup mailmain 2.1.5's spam filter set up to detect and DISCARD emails whose subjects contain certain spam keywords using the regular expressions shown below. ^subject:.*award ^subject:.*postcard ^subject:.*congratulation ^subject:.*lotto ^subject:.*lottery ^subject:.*lucky ^subject:.*winn ^subject:.*business.proposal ^subject:.*business.concern ^subject:.*verify.*account ^subject:.*charity ^subject:.*promotion ^subject:.*save.my.soul ^subject:.*\*\*\*SPAM\*\*\* ^subject:.*Update.Credit.Card ^subject:.*in.your.country ^subject:.*INVESTMENT.PROPOSAL ^subject:.*LEGITIMATE.TRANSACTION ^subject:.*GOOD.DAY!!! Trouble is: this spam filter seems to have no effect. Despite being setup as shown, every day I get numerous emails with subjects like these: POSTCODELOTERY PROMOTIONAL DEPARTMENT YOUR EMAIL WON THE LOTTERY AWARD NOTIFICATION PRIZE!! AWARD WINNING PROMOTION. Maybe the problem is that the spam filter regular expressions are case sensitive? (that would be quite useless) If I could see the files on l.m.o, maybe I could diagnose the problem myself. But as long as they remain closed to me ...
http://ftp.redhat.com/pub/redhat/linux/updates/enterprise/4AS/en/os/SRPMS/mailman-220.127.116.11-34.rhel4.2.src.rpm That's what we're running. We have made local modifications, but they're mostly cosmetic, and nothing has gone near the spam controls.
OK, case-sensitivity isn't the issue, I just checked the source, and it is passing the IGNORECASE flag to the regexp match when it runs it.
RPMs from redhat, eh? Does mofo/moco pay redhat for software support?
I should clarify one thing. I wrote: Despite being setup as shown, every day I get numerous emails with subjects like these: I should have written, ... numerous emails with subjects like these show up in the list of messages awaiting moderation. They are not discarded.
This still happening?
Dave, two weeks after I filed this bug, I took drastic action to deal with loads of apparently unfiltered spam. I changed the configuration for the list to simply discard all email from non-subscribers, and not keep any of it for "moderation". That's not an alltogether satisfactory solution either, because now I have no way of find the occasional (but rare) email that really should go through, and forwarding it. But this workaround is the lesser of two evils, in my opinion. If you've taken some corrective action, I'm willing to reconfigure those accounts to stop discarding all non-subscriber email, and test the spam filter again for a few days. Have you taken corrective action?
10 days ago, when I added the previous comment to this bug, I restored the spam filter. The spam filter is supposed to discard any emails that match any of its regular expressions. But since then, I still find emails in the moderation queue, waiting to be approved, that clearly should have matched one (or more) of the spam regular expressions. For example, one of the spam regular expressions (shown in comment 0) is ^subject:.*winn That surely should have matched this email subject: Subject: World Spring Luckyday Winner... but it didn't. So, in answer to comment 5: yes, this is still happening.
A year later, let's try again. This still happening?
Closing as WORKSFORME. If this is still an issue, please reopen.
