I think that we have all used various mail clients in our time. I am just a fan of the conversations and labeling that comes with gmail, and I use their web interface most often. But, there are still those times when a mail client will be best, like when you want to sign your email with your gpg key.
So I have been using evolution because it came with ubuntu, and I actually like it quite a bit. But my friend Trevor swears by Thunderbird so, I thought that I would give it a shot. Thunderbird is clean, easy to use, pretty easy to configure, and seems to work rather well. I like the way that the labeling feature works in it. But then that is all, email is the beginning, middle and end of Thunderbird. What about my calender, tasks, reminders, etc.? One of my only real reasons to use these clients is the calender and Mozilla hasn’t even made an attempt. I just can’t get over this. Nearly ever other client that I have ever used has some sort of calender function. And Evolution is integrated into the gnome desktop, making reminders, tasks, schedules, quick and accessible.
Continuing on, I can’t sign an email with my gpg key unless I install something else. Evolution has that built in.
In short, I will stick with Evolution. I would love to see Thunderbird have a full client that would rival Outlook, getting M$ Windows users to have a little more open source on their system.
When it all comes down to it though, all I hear is that I should use Mutt.
