Thunderbird replacement?

Back in the days I used Eudora as my email client, I didn’t like Outlook Express, the development kinda stopped on Eudora and I needed more out of my email client. After releuctantly using Outlook Express I was relieved to see Thunderbird and I made the switch. I never looked back again and never thought about Eudora again.
When I made the switch to Linux, Thunderbird was the obvious choice. I tried Evolution but that just didn’t do it for me.

With all the turmoil at Mozilla and the new MailCo that’s started I don’t know what to think. The future of Thunderbird isn’t clear, nothing has been said expect not to worry, yeah we heard that before. The two big names of Thunderbird development left Mozilla the last couple of days. Some people suggest there will be forking of Thunderbird.

While waiting for more news I decided to look around at other clients.Evolution is a no-no for me, I just don’t like it. Claws looks promising. I’m having some issues converting though, I tried the scripts Claws offers but with no luck. Converting by hand is a pain, I’ve got a lot of folders and several accounts. I’ll keep looking around, just in case Thunderbird becomes a wingless bird.
