This document covers the configuration process for lists.sr.ht.
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. Alternatively, it may be configured
to accept SMTP and run on another server. See
config.ini for details.
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.
lists.sr.ht-lmtp service and configure your MTA to forward emails
to the socket.
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.
On servers which should process forwarding and archival, install the
lists.sr.ht package and enable the
lists.sr.ht-process 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.
