I have been using KDE for a while, while I like many features I am looking for suggestions to the default email client:
Kmail - completely unusable for me and the only one which could maybe be integrated with kontacts, it could not receive mails from IMAP or pop or would receive only sometimes
Geary - good but too minimal, I need at least some kind of contact list and mailing lists feature, maybe this integrates with gnome contacts? I couldn’t find anything in settings
90% of the time I use web interfaces, but I often have spotty connectivity while boondocking. So I need a client that can get/send gmail POP3 in narrow windows of connectivity.
I started with thunderbird but something (can’t remember what) wasn’t working well. Ended up with Evolution. It also syncs well to google calendar and google tasks.
