before next release: disable backscatter in default installation
by Jo Rhett 08 Nov '22

Hi. There's a fairly simple problem here that needs to be addressed. And it's mostly a documentation/install problem. I'm hoping we can get this resolved before the next release. PROBLEM: Mailman comes out of the box ready to backscatter spam people. Yes, it's easy enough to fix. But because it comes stock this way, and is documented to install this way, most people install it to do this. Those of us who work in abuse departments are tired of hearing "well that's how Mailman works". We also object to having to teach people how to fix their mailman installations because it's not documented in the current manual. This is *exactly* like Sendmail 14 years ago. We didn't accept it then, and Sendmail fixed the problem. RESOLUTION: Mailman default installation should not backscatter in a default configuration. 1. Don't create backscatter aliases for subscribe/unsubscribe/etc by default. Nearly everyone uses web based signup. 2. Discard or hold messages from non-subscribers by default. I would think that it would be perfectly reasonable to have documentation on how to enable the 1980s-style -request / -subscribe etc aliases. However this documentation should have a note that this is against the AUP of nearly every network provider, and enabling it will likely cause them to get listed in various blacklists as a backscatter source. FYI: I know that this goes against the instincts of many old-time mailing list advocates here. But after dealing with a 10k/hour backscatter DoS my tolerance for this problem is understandably limited. Yes, it was a sweet day back in the 1980s. I was running a mailing list server and several UUCP gateways at the time, so I remember them well. But those days are past, and we need to deal with the reality of today. -- Jo Rhett Net Consonance : consonant endings by net philanthropy, open source and other randomness

Mailman, postfix and docker
by costavitorino＠gmail.com 28 Mar '21

Hi all I'm upgrading a mailman2 installation to mailman3. And I using a docker implementation, created by me and not Maxking's implementation. Everything is installed and is served correctly. I have created a postfix container that relays emails to a smtp server, and I can send emails by telnet from it. When I create a new thread in Hyperkitty, I receive an error from postfix container that the user (mailing list name) is not found. And I believe that is obvious because the aliases db are not accessible by postfix. So, my questions are: - Is there a way to share aliases db between containers(different hosts) of mailman and postfix? I thought about sharing volumes but I'm not quite sure if it's the best solution - I've seen: virtual_alias_maps = mysql:/etc/postfix/virtual/existing_aliases.cf, var/lib/mailman/data/virtual-mailman to add in postfix main.cf. Is it possible to do the same thing to aliases and transport_maps? And if so, how to set it in mailman configuration, because this is for mailman I've seen this thread: https://mail.python.org/archives/list/mailman-developers@python.org/thread/… And it seams kind or less the same situation. Does anyone have an idea or can give some pointers in how to accomplish this? Kind regards, Emanuel

Is it possible to use Postorius alongside the legacy interface?
by Joe Corneli 01 Jan '21

01 Jan '21

Hello, I wonder if it's possible for users to choose between the new Postorius interface and the old text-based interface? Some users might prefer the text-based interface (e.g., for accessibility or just familiarity); others may prefer the new interface (which does look quite snazzy!). But, I didn't find any documentation about switching between the two. Joe
