Unable to Create New Lists
by Phil Fonville June 1, 2007

June 1, 2007

My thanks to Dan Phillips, Mark Sapiro and any others who pointed out (correctly) that I needed fully qualified domain names for several items in mm_cfg.py. My problem evaporated after I changed DEFAULT_NNTP_HOST = 'bashful' DEFAULT_EMAIL_HOST = 'bashful' DEFAULT_URL_HOST - 'bashful' To DEFAULT_NNTP_HOST = 'bashful.troxlerlabs.local' DEFAULT_EMAIL_HOST = 'bashful.troxlerlabs.local' DEFAULT_URL_HOST - 'bashful.troxlerlabs.local' Thanks again.

a question about unadvertised lists and spam
by Dennis Morgan June 1, 2007

June 1, 2007

We have a site: http://eaachat.org/ with several mailing lists. We have some lists advertised on a non-default public list info page that we "branded" (thank you Mark for your help!) here: http://eaachat.org/maillist.html and shows only the publicly accessible pages. These pages have a mailto: owner(a)eaachat.org which is forwarded to list(a)eaachat.org. We all have various filters set in our MUA to cope with this. We check the moderator pages of the public lists frequently for legitimate help requests, in other words the admins are the spam filters for the domain. The default mailman list info page is here: http://lists.eaachat.org/mailman/listinfo All lists are closed to non member posts and the subscribe policy is confirm and approve. My question is - are spamers able to pick up lists from the default (but not easily accessible) default mailman listinfo page and start bombarding us with spam on all lists? Or should I set the "Advertise this list" option to "no" for the lists on the default listinfo page? Thank you, Dennis

odd empty bounce message generated upon posting to a mailing list
by Jon Pauli June 1, 2007

June 1, 2007

Hello, I have been looking around in the docs and have not seen anything that matches my issue. I have a couple of mailing lists and every time anyone- member or non-member posts, everything works fine but the list owner gets 1)An uncaught bounce notification containing an empty attachment called ForwardedMessage.eml. Thunderbird is the MUA so I'm guessing it is responsible for determining how to interpret the attachment, but even if I save it as a text file it is a 2 byte long file with no visible characters in it...I didn't take a hex editor to it. I understand why listowner gets these, I'm just not sure how it can work with a 2 byte file and no headers ;) 2. An email where no subject and no sender appear in the MUA. The headers are as follows: Delivered-To: me(a)mydomain.com Return-Path: < mailman-bounces(a)mail.mydomain.com> Received: from [192.168.10.22] (softdnserr [127.0.0.1]) by mail.mydomain.com with esmtp; Thu, 31 May 2007 09:57:36 -0500id 00A9A0CA.465EE260.00010B2E Sender: mailman-bounces(a)mail.mydomain.com Errors-To: mailman-bounces(a)mail.mydomain.com Message-ID: <courier.465EE260.00010B2E@mydomain> Date: Thu, 31 May 2007 09:57:36 -0500 To: undisclosed-recipients: ; The interesting things I noticed are: 1. The Received: header line is wrong. The mail server has a DNS server running on it as well as the MTA. its IP is 192.168.11.22 NOT 10.22 There is no 192.168.10.22 on my network. This happens only for mailman emails. I don't recall having to set any IPs when I set up mailman. What is wrong here? 2. The end of the Message-ID: line contains only mydomain, not say, mydomain.com like non-mailman emails. 3. There is no Sender showing up in the MUA but the Sender: header is present. It looks like Thunderbird maybe uses the From: header instead of the Sender header despite naming the column where this would appear "Sender". I'd appreciate any thoughts or insight into this. I am confused.

Point of Clarification for announcement lists
by bishop＠disinfo.net June 1, 2007

June 1, 2007

Hi all, I'm a serious newbie to Mailmain, but I've worked through most of my installation and basic configuration issues to get it up an running. I do need some clarification regarding announcement lists. The instructions tell me to create a new directory: "In Mailman 2.1.x you can customize the welcome message. Create a directory lists/<yourlist>/en (assuming English :) and copy templates/subscribeack.txt to this directory. Then edit this file for your specific wording. Mailman will use this specialized template for the English welcome messages." I'm assuming that this directory is in the root of the /usr/lib/Mailman/ directory. Is this correct? I've created the following directory structure: /usr/lib/mailman/Lists/XXXX-high-school-announcements/en and copied over the subscribeack.txt file. I've edited the subscribeack.ext file to reflect what I want the welcome message to say, but it doesn't seem to be working. I think I need to configure Mailman to use the new template, but I couldn't find any such instructions. Am I missing something? Any help is greatly appreciated! Thanks, David

ANSWER: Integrating PHP to Mailman
by Curtis Preston June 1, 2007

June 1, 2007

As some of you are aware, I've been integrating Mailman with PHP to integrate it into Joomla!. I had a version that did it using command line options, but that didn't work for a lot of people, so I did some work to figure out how to do it via the file_get_contents function in PHP. I have pulled it off and my Joomla! component is just about ready to go out to the community, but I thought I'd send a non-Joomla! version to show how to use PHP to administer Mailman. Attached is a demo script that will demonstrate how I did this. Hopefully you should be able to look at the script and its output and learn how to do what YOU need to do. To use the script, put it in the doc directory of your web server, calling it mailman.php. Then edit it and change the value of $domain to your domain, change $email to some valid email address, and change $adminpw to the admin password of your site. Leave diag at 1 to see the most information. Set it to 0 to turn off most of it, and set it to 2 for debugging. Then run yourdomain/mailman.php and watch the show. 1. List all the lists on your server 2. List all the lists that the email address you supplied is subscribe to, and how they're subscribed (digest or regular) 3. Do #2 again in a different way 4. Unsubscribe the email address you gave from all lists 5. Subscribe the email address you gave to all lists 6. Change the subscription to digest mode on all lists Here 'tis: -------cut and paste----- <? #List all lists $domain="domain.com"; $email="user(a)domain.com"; $adminpw="password"; $diag=1; #Build an array of all lists and their descriptions print "<html><body>\n" ; #Build the command to list all lists $adminurl="http://" . $domain . "/mailman/admin"; if ( "$diag" == 1 ) {print "<br><b>adminurl=</b>$adminurl\n" ;} #Run the command $content=file_get_contents("$adminurl","FALSE"); #Split the output into an array that we can loop through $array = preg_split('/\n/',$content); #For each line in the output foreach ($array as $element) { #As soon as we see the first line of the list of lists, say so if ( preg_match("/a href=.*strong.*strong/", "$element") ) { $table="on";} if ( "$diag" == 2 ) {print "<br>$table:$element";} if ( "$table" == "on" ) { #We're inside the table if ( preg_match("/a href=.*strong.*strong/", "$element") ) { #If it's the line with the listname... if ( "$diag" == 2 ) {print "<br>list:$element\n";} $listname = preg_replace("/.*href=./","","$element") ; $listname = preg_replace("/.>.*/","","$listname") ; $listname = preg_replace("/.*\//","","$listname") ; if ( "$diag" == 2 ) {print "<br>listname:$listname\n";} } else { if ( "$diag" == 2 ) {print "<br>desc:$element\n";} if ( preg_match("/<td>.*<.td>/", "$element") ) { #If it's the line with the description $description = preg_replace("/.*<td>/","","$element") ; $description = preg_replace("/<.td>.*/","","$description") ; $description = preg_replace("/<\/*em>/","","$description") ; $lists["$listname"] = "$description"; if ( "$diag" == 2 ) {print "<br>description:$description\n";} } } #When the table ends, there's no more work to do if ( preg_match("/<.table>/", "$element") ) { $table="off";} } } if ( "$diag" == 1 ) {print "<table border=1>\n";} if ( "$diag" == 1 ) {print "<tr><td>Listname</td><td>Description</td></tr>\n";} #Loop through the associative array of lists and descriptions and print them out foreach ($lists as $listname => $desc) { if ( "$diag" == 1 ) {print "<tr>\n";} if ( "$diag" == 1 ) {print "<td>$listname</td>\n";} if ( "$diag" == 1 ) {print "<td>$desc</td>\n";} if ( "$diag" == 1 ) {print "</tr>\n";} } if ( "$diag" == 1 ) {print "</table>\n";} if ( "$diag" == 1 ) {print "<table border=1>\n";} if ( "$diag" == 1 ) {print "<tr><td>Listname</td><td>Regular/Digest</td></tr>\n" ;} #For each list foreach ($lists as $listname => $desc) { #Find email in list #Build a command to list if a member is in a given list $findemailurl="http://" . $domain .

Low level smtp error: Server not connected
by Leonard Jacobs June 1, 2007

June 1, 2007

I am trying to run Mailman 2.1.9 on a CentOS 4 server with postfix 2.4.1. I had Mailman 2.1.5 running on a slower system and wanted to offload some apps to this newer server but am having problems. check_perms has no errors. Creating lists works fine and when postings are submitted the messages are delivered to the list admins re posting verifications. But only a few of the messages are getting delivered. logs/smtp-failure shows many of this type of error: "delivery to someone(a)gmail.com failed with code -1: (104, 'Connection reset by peer')" I am also seeing many " Low level smtp error: Server not connected, msgid" errors. I did try all the suggested fixes in the FAQ including adding the line to get error output in the logs/error file. And this file is showing successful delivery, such as "May 26 16:33:44 2007 qrunner(20744): reply: '250 2.1.5 Ok\r\n' May 26 16:33:44 2007 qrunner(20744): reply: retcode (250); Msg: 2.1.5 Ok May 26 16:33:44 2007 qrunner(20744): send: 'rcpt TO:<somebody(a)surewest.net>\r\n"" but the majority of the messages are simply stuck in the qfiles/out and qfile/rety directory. I am running python 2.5.1 so that I could get the error logging to work but this problem happened with python 2.3. Any suggestions would be greatly appreciated since my mailing list no longer works at all. Thanks.
