Hi, I've been using KMail at home and work as my email client and have been fairly (but not completely) satisfied. Recently, I changed to using Thunderbird at work, very easy since my work email uses an IMAP server. But my personal email accounts all use POP servers. Does anyone have experience moving between the two systems? Do they use the same formats for folders and saving email? And if I end up not liking Thunderbird as much as I currently do, will I be able to change back?

Try Thunderbird help. At the project web site you can find simple steps how to migrate from Kmail to Thunderbird and back. -- Mirko
