Hello Mailman Users,
Are there instructions on importing a Mailman 2 list into a Mailman 3 core installation only? Does the import21 script not need Django/Postorius/Hyperkitty?
import21 requires only Mailman core.
It seems Django is required to import archives I guess because of the use of Hyperkitty. How about importing archives without having a Django installation? Is that what the prototype archiver for?
The only current archive import we support is django-admin hyperkitty_import which imports archive .mbox files into HyperKitty.
The prototype archiver is just a maildir format collection of messages.
Converting an mbox file to a maildir is trivial.
from mailbox import Maildir, mbox mb = mbox('/path/to/mbox', create=False) md = Maildir('/path/to/maildir', create=True) for msg in mb: md.add(msg)
We are getting ready to start working on a custom forum application for Mailman 3 (called Empathy) and I am would like to import some mailman 2 archives into the development server to work with.
First you have to decide how Empathy will store messages. Look at <https://gitlab.com/mailman/hyperkitty/-/blob/master/hyperkitty/management/commands/hyperkitty_import.py#L93>. This is how HyperKitty gets messages from a mbox and adds them to its database. It's actually fairly simple - a lot of the code is handling exceptions due to defective messages.
Presumably Empathy will have a method for adding a message to the archive, so importing is just getting messages from the mbox and using Empathy's method to add it.
