I am looking for a solution to my email problem. I need a searchable backup system for all my emails and make room on the servers. Preferrably in a format that's (:gitannex: #gitAnnex) sync friendly (e.g. all just .eml files). A terminal-based Thunderbird alternative would also be nice. I see there's #mbsync#mutt#neomutt#supMail#nmail#alpine and so many more but no concise overview with feature comparison. What would you recommend?
