Web links in templates - is this non-default?
by Andy Smith June 19, 2022

June 19, 2022

Hi, From Mailman 2 I am used to various administrative emails having web links in them for ease of use. For example, when confirming your subscription to a list I am used to the confirmation email having both an embedded code for replying back and also a link to the web interface for confirming by web. On a new install of mailman3-full on Debian 11 I am not seeing any web links, only text regarding replying by email, how to change options by email, etc. Am I right in thinking that this is intentional, it is not some simple thing that I missed or forgotten to enable? I'm assuming because mailman3 can function without any web interface so it was considered that adding links to Postorious by default would not be the correct thing to do? If that is the case, is the correct way to achieve what I want to add a bunch of custom templates? It seems like it might be a common desire, so have anyone done this already? I searched around but I've found it difficult to come up with good search terms for this. Thanks, Andy

New install - Where's 'changeme@example.com' coming from?
by Andy Smith June 18, 2022

June 18, 2022

Hi, I've just installed mailman3 (well, mailman3-full) on a Debian 11 host from Debian packages. I thought I'd gone through /etc/mailman3/mailman.cfg thoroughly, but I am seeing the From: address changeme(a)example.com in some administrative notifications. Now, when I search for help on this everything says that I have not set site_owner in /etc/mailman3/mailman.cfg, but I have! As an example of what I am seeing, when I use the web interface to unsubscribe a list member, the member themself gets a notification as expected: From: testing-bounces(a)lists.strugglers.net To: andy-again(a)strugglers.net Subject: You have been unsubscribed from the Testing mailing list but the list's owner gets one from "changeme(a)example.com": From: changeme(a)example.com To: testing-owner(a)lists.strugglers.net Subject: Testing unsubscription notification andy-again2(a)strugglers.net has been removed from Testing. I can't for the life of me work out where this is coming from: $ sudo ack site_owner /etc/mailman3 /etc/mailman3/mailman.cfg 28:site_owner: postmaster(a)lists.strugglers.net $ sudo ack changeme /etc/mailman3 (no output) It's not in any of the sqlite DBs either (still on sqlite while testing things out): $ sudo sqlite3 /var/lib/mailman3/data/mailman.db .dump | grep -i changeme $ sudo sqlite3 /var/lib/mailman3/web/mailman3web.db .dump | grep -i changeme So where can this possibly be coming from? I have not yet configured the MTA (Exim) for delivering to Mailman, and I haven't done anything special about sending settings: [mta] # … outgoing: mailman.mta.deliver.deliver smtp_host: localhost smtp_port: 25 configuration: python:mailman.config.exim4 Thanks, Andy

Removing the option to delete a list on the Postorious interface
by Wong, Wesley June 14, 2022

June 14, 2022

Hi, I have a question on the Postorious web interface in Mailman 3. I have found that a list owner can delete a list through the Postorious interface if they have the role of owner to the list. I wanted to have it either disabled or removed but I am not sure where to look to make changes to it. I would rather remove it from the interface totally so it would be done from the command line. Any help would be greatly appreciated. wesley

Sender filters accept_these_nonmembers from another list
by Bob Williams June 4, 2022

June 4, 2022

I would like to allow all the members of list_A to post to list_B. list_A contains about 50 addresses, so rather than add each one to the 'List of non-member addresses whose postings should be automatically accepted' (Privacy options > Sender filters > Nonmember filters) I have added "@list_A" in that box. However, I still get asked to authorise postings to list_B by members of list_A. Both list_A and list_B are in the same domain and hosted on the same cPanel server. Have I misunderstood how to do this, or is there another setting somewhere else that I need to toggle? Thank you Bob -- Bob Williams

Filter Rule precedence, Sender filters or Spam filters?
by Bob Williams June 2, 2022

June 2, 2022

If I have a list of addresses/domains in Sender filters > List of non-member addresses whose postings will be automatically discarded and also a Spam filter containing the rule X-Spam-Status:\s+Yes which one is applied first for a message that satisfies both? Bob -- Bob Williams

How to wrap text in archived messages
by Mark Dale June 1, 2022

June 1, 2022

Hi, I'm looking for a way to wrap lines in archived messages. Messages from some mail clients (eg. Gmail) have their lines wrapped to 72 chars in the archived version, while archived messages from others (eg. Thunderbird, Outlook) display unwrapped lines forcing the reader to scroll horizontally. Looking at the HTML page source -- in both cases (wrapped and unwrapped) I see the message content is enclosed by PRE tags. <HR>  <PRE> Lorem ipsum dolor sit amet, consectetur ... Ut enim ad minim veniam, quis nostrud ... </PRE>  <HR> The template (article.html) contains the following: ... <HR>  %(body)s  <HR> ... From what I can figure out, the PRE tags come from .../mailman/Mailman/Archiver/HyperArch.py in a block of code lines 1290 to 1314 ... /////////////////////////////////////////// def format_article(self, article): # called from add_article # TBD: Why do the HTML formatting here and keep it in the # pipermail database? It makes more sense to do the html # formatting as the article is being written as html and toss # the data after it has been written to the archive file. lines = filter(None, article.body) # Handle <HTML> </HTML> directives if self.ALLOWHTML: self.__processbody_HTML(lines) self.__processbody_URLquote(lines) if not self.SHOWHTML and lines: lines.insert(0, '<PRE>') lines.append('</PRE>') else: # Do fancy formatting here if self.SHOWBR: lines = map(lambda x:x + "<BR>", lines) else: for i in range(0, len(lines)): s = lines[i] if s[0:1] in ' \t\n': lines[i] = '<P>' + s article.html_body = lines return article //////////////////////////// And the lines in that block that seem responsible for the PRE tags are ... lines.insert(0, '<PRE>') lines.append('</PRE>') My question is: Can those PRE tags be removed and replaced with something equivalent to PHP's "nl2br" (which inserts a line break BR in place of new line entries)? A Google search for such an equivalent gives me ... def nl2br(s): return '<br />\n'.join(s.split('\n')) With zero understanding of Python my attempts to implement this have failed so far and I may well be barking up the wrong tree completely. Any clues or pointers gratefully received. Thanks.
