Hi,

We have a user who is proposing that reply messages from a mailing list should be in the following format:

Re: [MM3-users] Ubuntu 24.04 upgrade notes

and not

[MM3-users] Re: Ubuntu 24.04 upgrade notes

Their reason... is that mailman2, and other lists, used to do it that way.

I myself am agnostic about the difference, and probably prefer to keep things the way mailman3 recommends.

The questions are:

1. What could be explained to the user to convince them the new method is preferable.

This is to support prefixes that contain %d for the message number. Suppose the prefix is [List #%d] and a post to the list has prefixed subject

[List #501] A Subject.

With old style, a reply a few posts later might have subject

Re: [List #504] A Subject.

But it is not a reply to [List #504], it is message [List #504] replying to A Subject. so the appropriate subject is

[List #504] Re: A Subject.

2. Can this be customized with a Setting? (Not that we will end up modifying it. Just curious).

In mailman 2.1 this was called OLD_STYLE_PREFIXING and prefixes without %d could optionally do it the old way or the new way , but prefixes with %d always did it the new way.

For Mailman 3 we always do it the new way even if the prefix does not contain %d.

That seems wrong. It's not a reply to a message from "[MM3-users]", it's a reply sent to "[MM3-users]".

[MM3-users] Re: Ubuntu 24.04 upgrade notes

That looks right. It's a message from "[MM3-users]", and that message is a reply to "Ubuntu 24.04 upgrade notes".

Their reason... is that mailman2, and other lists, used to do it that way.

And now Mailman 3 does it better.
