Hi there, we have just started with internal tests around Mailman3 before we want to use it productively. Our instance runs on a virtualised Debian server. We have now started to work with the templates and created a new template ‘list:user:action:subscribe.txt’ under /var/lib/mailman3/templates/site/de. Unfortunately, we can't find out how to customise the subject of the email. Can anyone help us here? Regards Johannes

You can add a prefix in Settings > List Identity > Subject Prefix. If you want the conventional square brackets "[]" you must put them in yourself. If you want a serial number, you can add a Python "%d" spec (you can specify the width and zero-padding as usual). You cannot customize the serial number itself. I believe it resets every time the digest volume number is incremented.
If you want more than that, that's the responsibility of the MUA.

Hi, thanks for your feedback. We now the setting for the prefix but we would like to completely customize the subject. At the moment the subject looks something like this: "Your confirmation is needed to join the placeholder@placeholder.com mailing list." This text needs to be customized as we only have older users which need it in their native language (German). ;) Thanks and regards

If you set the list's preferred language to German, the subject should be translated.
