Our current mailing list host, Linux= Foundation, has indicated for years that they have wanted to stop hosting = mailing lists, which would mean the bitcoin-dev mailing list would need to = move somewhere else.

In this email, we will go over some of the history, opti= ons, and invite discussion ahead of the cutoff. We have some ideas but want= to solicit feedback and proposals.

Background
=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D

The bitcoin-dev mailing list was originally hosted on S= ourceforge.net. The bitcoin development mailing list has been a source of p= roposals, analysis, and developer discussion for many years in the bitcoin = community, with many thousands of participants. Later, the mailing list was= migrated to the Linux Foundation, and after that OSUOSL began to help.
=
Linux Foundation first asked us to move the mailing list in 2017. They = internally attempted to migrate all LF mailing lists from mailman2 to mailm= an3, but ultimately gave up. There were reports of scalability issues with = mailman3 for large email communities. Ours definitely qualifies as.. large.=

2019 migration plan: LF was to turn off mailman and all lists would= migrate to the paid service provider groups.io. Back then we were given accounts to try the groups.io interface and admi= nistration features. Apparently we were not the only dev community who resi= sted change. To our surprise LF gave us several years of reprieve by instea= d handing the subdomain and server-side data to the non-profit OSUOSL lab w= ho instead operated mailman2 for the past ~4 years.

OSUOSL has for d= ecades been well known for providing server infrastructure for Linux and Op= en Source development so they were a good fit. This however became an added= maintenance burden for the small non-profit with limited resources. Severa= l members of the Bitcoin dev community contributed funding to the lab in su= pport of their Open Source development infrastructure goals. But throwing m= oney at the problem isn=E2=80=99t going to fix the ongoing maintenance burd= en created by antiquated limitations of mailman2.

Permalinks
=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D

Linux Foundation has either offered or a= greed to maintain archive permalinks so that content of historic importance= is not lost. Fortunately for us while lists.linuxfoundation.org mailman will go do= wn, they have agreed the read-only pipermail archives will remain online. S= o all old URLs will continue to remain valid. However, the moderators stron= gly advise that the community supplements with public-inbox instances to ha= ve canonical archive urls that are separate from any particular email softw= are host.

Public-Inbox
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
https:= //public-inbox.org/README.html

=E2=80=9CPublic Inbox=E2=80=9D de= centralized archiving - no matter what mailing list server solution is used= , anyone can use git to maintain their own mailing list archive and make it= available to read on the web.

Public Inbox is a tool that you can r= un yourself. You can transform your mbox file and it makes it browsable and= viewable online. It commits every post to a git repository. It's kind = of like a decentralized mail archiving tool. Anyone can publish the mail ar= chive to any web server they wish.

We should try to have one or more= canonical archives that are served using public-inbox. But it doesn't = matter if these are lost because anyone else can archive the mailing list i= n the same way and re-publish the archives.

These git commits can al= so be stamped using opentimestamps, inserting their hashes into the bitcoin= blockchain.

LKML mailing list readers often use public-inbox's = web interface, and they use the reply-to headers to populate their mail cli= ent and reply to threads of interest. This allows their reply to be properl= y threaded even if they were not a previous subscriber to that mailing list= to receive the headers.

public-inbox makes it so that it doesn'= t really matter where the list is hosted, as pertaining to reading the mail= ing list. There is still a disruption if the mailing list goes away, but th= e archives live on and then people can post elsewhere. The archive gets dis= connected from the mailing list host in terms of posting. We could have a f= ew canonical URLs for the hosts, separate from the mailing list server.

mailman problems
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Over the years we have identified a number of problems with mailman2 e= specially as it pertains to content moderation. There are presently a handf= ul of different moderators, but mailman2 only has a single password for log= ging into the email management interface. There are no moderator audit logs= to see which user (there is no concept of different users) acted on an ema= il. There is no way to mark an email as being investigated by one or more o= f the moderators. Sometimes, while investigating the veracity of an email, = another moderator would come in and approve a suspect email by accident.
Anti spam has been an issue for the moderators. It's relentless. W= ithout access to the underlying server, it has been difficult to fight spam= . There is some support for filters in mailman2 but it's not great.
=
100% active moderation and approval of every email is unsustainable for= volunteer moderators. A system that requires moderation is a heavy burden = on the moderators and it slows down overall communication and productivity.= There's lots of problems with this. Also, moderators can be blamed whe= n they are merely slow while they are not actually censoring.

Reject= ion emails can optionally be sent to bitcoin-dev-moderation@lists.ozlabs.= org but this is an option that a moderator has to remember to type in e= ach time.

Not to mention numerous bugs and vulnerabilities that have= accumulated over the years for relatively unmaintained software. (Not disc= losed here)

Requirements and considerations
=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
Looking towards the future, there are a number of properties that seem= to be important for the bitcoin-dev mailing list community. First, it is i= mportant that backups of the entire archive should be easy for the public t= o copy or verify so that the system can be brought up elsewhere if necessar= y.

Second, there seems to be demand for both an email threading inte= rface (using mailing list software) as well as web-accessible interfaces (s= uch as forum software). There seems to be very few options that cater to bo= th email and web. Often, in forum software, email support is limited to ema= il notifications and there is limited if any support for email user partici= pation.

Third, there should be better support for moderator tools an= d management of the mailing list. See above for complaints about problems w= ith the mailman2 system.

Burdens of running your own mailing list an= d email server
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

If you have never operated y= our own MTA you have no idea how difficult it is to keep secure and functio= nal in the face of numerous challenges to deliverability. Anti-spam filteri= ng is essential to prevent forwarding spam. The moment you forward even a s= ingle spam message you run the risk of the server IP address being added to= blacklists.

The problem of spam filtering is so bad that most IP ad= dresses are presumed guilty even if they have no prior spam history, such a= s if their network or subnetwork had spam issues in the past.

Even i= f you put unlimited time into managing your own email server, other people = may not accept your email. Or you make one mistake, and then you get into p= ermanent blacklists and it's hard to remove. The spam problem is so bad= that most IPs are automatically on a guilty-until-proven-innocent blacklis= t.

Often there is nothing you can do to get server IP addresses remo= ved from spam blacklists or from "bad reputation" lists.

I= ronically, hashcash-style proof-of-work stamps to prevent spam are an appea= ling solution but not widely used in this community. Or anywhere.

In= finite rejection or forwarding loops happen. They often need to be detected= through vigilance and require manual sysadmin intervention to solve.
Bitcoin's dev lists being hosted alongside other Open Source projects= was previously protective. If that mailing list server became blacklisted = there were a lot of other people who would notice and complain. If we run a= Bitcoin-specific mail server we are on our own. 100% of the administrative= burden falls upon our own people. There is also nothing we can do if some = unknown admin decides they don't like us.

Options
=3D=3D=3D= =3D=3D=3D=3D

Web forums are an interesting option, but often don'= ;t have good email user integration. At most you can usually hope for email= notifications and an ability to reply by email. It changes the model of th= e community from push (email) to pull (logging into a forum to read). RSS f= eeds can help a little bit.

Many other projects have moved from mail= ing lists to forums (eg https://discuss.python.org/ =E2=80=93 see https://lwn.net/Articles/901744/ ; or https://ethrese= ar.ch/), which seem easier to maintain and moderate, and can have lots = of advanced features beyond plaintext, maybe-threading and maybe-HTML-marku= p.

Who would host the forum? Would there be agreement around which f= orum software to use or which forum host? What about bitcointalk.org or delvingbitcoin.org? There are many o= ptions available. Maybe what we actually want isn=E2=80=99t so much a discu= ssion forum, as an 'arxiv of our own' where anons can post BIP draf= ts and the like?

Given the problems with mailman2, and the decline o= f email communities in general, it seems that moving to mailman3 would not = be a viable long-term option. This leaves us with Google Groups or groups.io as two remaining opti= ons.

groups.io is= an interesting option: they are a paid service that implements email commu= nities along with online web forum support. However, their public changelog= indicates it has been a few years since their last public change. They mig= ht be a smaller company and it is unclear how long they will be around or i= f this would be the right fit for hosting sometimes contentious bitcoin dev= elopment discussions...

Google Groups is another interesting option,= and comes with different tradeoffs. It's the lowest effort to maintain= option, and has both an email interface and web forum interface. Users can= choose which mode they want to interact with.

For the Google Groups= web interface, you can use it with a non-gmail account, but you must creat= e a Google Account which is free to do. it does not require any personal in= formation to do so. This also allows you to add 2FA. Non-gmail non-google u= sers are able to subscribe and post email from their non-gmail non-google e= mail accounts. Tor seems to work for the web interface.

Will Google= shut it down, will they cut us off, will they shut down non-google users? = The same problem exists with other third-party hosts.

The moderation= capabilities for Google Groups and groups.io seem to be comparable. It seems more likely that Goog= le Groups will be able to handle email delivery issues far better than a sm= all resource-constrained operation like groups.io. ((During feedback for this draft, luke-jr indica= tes that Google Workspaces has been known to use blacklisted IPs for busine= ss email!))

On the other hand, groups.io is a paid service and you get what you pay for...= hopefully?

Finally, another option is to do literally nothing. It&#= 39;s less work overall. Users can switch to forums or other websites, or pr= ivate one-on-one communication. It would remove a point of semi-centralizat= ion from the bitcoin ecosystem. It would hasten ossification, but on the ot= her hand it would hasten ossification and this could be a negative too. Mod= erators would be less of a target.

Unfortunately, by doing nothing, = there would be no more widely used group email communication system between= bitcoin developers. Developers become less coordinated, mayhem and chaos a= s people go to different communication platforms, a divided community is mo= re vulnerable, etc. BIP1 and BIP2 would need to be revised for other venues= .

The main categories of what to move to are: web forums, mailing li= sts, and hybrids of those two options. Most everything is either self-hoste= d or you pay someone else to host it. It's kind of the same problem tho= ugh. It largely depends on how good is the software and unfortunately runni= ng your own MTA that forwards mail is not a good option.

Going forwa= rd
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

We'd like to invite feed= back and proposals from the community, and see what options are available. = One potential option is a migration to Google Groups, but we're open to= ideas at this point. We apologize for any inconvenience this disruption ha= s caused.
