[MM3-users] Re: Migration from 2.1 to 3

I've found something, the imported list preferred language is Spanish (es), changing it to 'en' :

mailman shell -l lispruebas@mailman3.agro.uba.ar m._preferred_language 'es' m._preferred_language = 'en'

seems to fix everything, as soon as i hit ctrl+d the messages are delivered properly.

Even when i set it to french which has the same charset as spanish it works as expected. Any ideas why?
