I have been using Evolution as a mail client for probably more than a year now. Personally, I’ve never had much use for the calendar, notes or any other feature in the application other than mail account management. To some it may seem obvious that a switch to Thunderbird would be sensible but old habits die hard sometimes and with the hope of Evolution coming out with some new features, I stuck it out for a while longer. However; last night I decided to set Thunderbird up and take a look at it at the very least.
A brief glance turns into a project… As I opened up Thunderbird and looked at the interface and the built in wizards for importing, suddenly the prospect of switching looked very appealing. The immediate standout differences were the ability to change your theme, add extensions, manage rss feeds (was something I was really hoping Evolution would have added) and the option to customize the toolbar were all selling features on making the switch.
Importing and Exporting… After several google searches and attempts to use the built in tools for Evolution and Firefox I quickly discovered there would be no effective way to move all of my settings from Evolution to Thunderbird through either of their built in wizards. This is something that both applications could use some work on (I can understand slightly why a developer may not consider how to move to a different application a huge priority but at least make it easy for people to move *to* your application). I ended up manually creating all my accounts all over again (6 in total) and I will need to create all new rules for anything that was previously set up but I can live with that. I basically moved everything from my hidden evolution home directory /home/username/.evolution/mail/local/Inbox/ (keep in mind that Evolution creates 4 files for each account but you need only move one which is the generic one named with only the account username) into the /home/username/.thunderbird/ *tokenstrangenumber*.default/mail/Local Folders/Inbox.sbd/ After this is done, you need to close Thunderbird and then restart it. You will then see all of your folders containing mail from Evolution appear at the bottom left of your Thunderbird Folders section. I just used drag and drop to move all of the copied mail folders into their respective account locations. The whole process didn’t take that long, but it was well worth it in the end.
What I really wanted to be able to do was combine viewing RSS feeds with also catching up on my mail. Evolution is yet to offer this feature but Thunderbird supports RSS feeds. Thankfully Thunderbird does have an RSS account creator and allows you to import a feedlist file. I had been previously using Liferea which is a very nice application in its own right, but since I could combine both features in one application, I imported my feedlist.opml (typically located in /home/username/.liferea/) and it came in nicely although it did not place everything into nicely orgranized folders as I had done in Liferea. A bit of renaming of the feeds in Thunderbird fixed this issue.
I mentioned before that I didn’t have any use for the calendar in Evolution. Although this is true, I did want something that could remind me of important and upcoming dates or events. I found a very useful Thunderbird extension for this (this can be used for Firefox as well if you prefer). The extension is called Reminder Fox — here is a pic of how it works:

This appears as a string in the bottom right hand corner and you can add events to it by clicking on it. To see what events are approaching, you need only hold your mouse cursor over it. This extension is simple, works well and does exactly what it is designed to do. Just what I wanted. I didn’t need a massive calendar program like the one in Evolution. As much as I like Gnome and will continue to use it, Evolution could use some improvement (I’ll save that for a future entry)
Once I had this set up, modified my theme to my liking, I had everything in place. All that is left to do is create my rules which shouldn’t take too long. Overall, it was well worth the migration. I’ve been using Firefox for a long time now and make use of a lot of the extra features in it. It’s no surprise that Thunderbird has accomplished a similar degree of customization and effectiveness in its design.
