The 9front project maintains several mailing lists which users should subscribe to and follow. To subscribe to a mailing list, send an e-mail message to list-owner@9front.org, where list is the name of the mailing list. That address is an automated subscription service. In the body of your message, on a single line, you should include the subscribe command.

After subscribing, list messages are sent to and received from list@9front.org, where list is the name of the mailing list.

The lists are as follows:

To unsubscribe from a list, you will again send an e-mail message to list-owner@9front.org, this time containing, on a single line, the unsubscribe command.

Note: The following domains currently block mail from 9front.org: eff0ff.net, hostmail.co.jp, live.com, m5.chicago.il.us, mailfence.com, outlook.com, pheist.org, posteo.de, posteo.net, strassen.ch

Mailing list archives are available via 9p:

Each of these directories contains messages sent to the respective mailing list in mdir format, one message per file. Erick Quanstrom's nupas upas/fs (now merged with 9front upas) can mount these directories as mailboxes, for reading directly with a mail client. Note: Opening large mailboxes over a slow 9p link will be very slow.
