| lists.sr.ht installation |
lists.sr.ht is the mailing list service for lists.sr.ht. There are a number of important components:
- The LMTP daemon, which receives incoming email from a separate mail server (e.g. postfix), does minimal processing & validation, and dispatches it to the celery worker.
- The celery worker is distributed on as many cores and/or servers as you like and can take its time processing emails. It's responsible for forwarwding and archiving emails.
- The web interface displays the archive, manages subscriptions, etc, on the web.
LMTP daemon installation
The LMTP daemon is available in the lists.sr.ht package, at the binary
lists-srht-lmtp. It needs to run on your mail server, and you need to
configure your MTA to forward emails to it.
The LMTP daemon uses the same config file as the others, and there are some options there specifically catered to it. The most important is the Unix socket path for the LMTP socket - and the user/group it should be assigned to. Make sure that this is readable and writable by your MTA.
Enable the lists.sr.ht-lmtp service and configure your MTA to forward emails
to the socket.
Mail server setup
The precise configuration of your mail server is a very subjective matter, and we don't have a one-size-fits-all solution to give you. Here's an example of forwarding to lists.sr.ht with postfix:
# main.cf
local_transport = local:$myhostname
transport_maps = hash:/etc/postfix/transport
# /etc/postfix/transport
lists.sr.ht lmtp:unix:/tmp/lists.sr.ht-lmtp.sock
sr.ht local:sr.ht
This forwards mail to @lists.sr.ht to the LMTP socket, and processes mail to @sr.ht to local mailboxes. This is just one part of your setup, however, and the remainder of your postfix (or other mail server) configuration is left as an exercise to the reader.
Celery worker installation
On servers which should process forwarding and archival, install the
lists.sr.ht package and enable the lists.sr.ht-worker service. Make sure you
review the config file for worker-specific options as well. The Redis instance
you use here should be shared with the LMTP daemon and other worker nodes to
ensure that messages can be distributed correctly.
Web service installation
The lists.sr.ht web service is a standard sr.ht web service and can be installed through the standard procedure.

A minimal local mail server setup which can be used to work on lists.sr.ht is described in this article.
