I’m trying to do this the other way around. I’ve been using Thunderbird for a while and all my saved mail is in whatever format Thunderbird uses, but it’s struck me that Thunderbird doesn’t provide me with anything that kmail + bogofilter would, whereas by using kmail I get all the nice KDE integration. Now I can save each email as a .eml file and import those into kmail but that’s going to take a very long time; has anyone had success doing it that way?
