I have been using Evolution email client for more than three years from now. I have moved my mails stored in the .evolution folder from computer to computer. Evolution has handled literally millions of emails for me in these years. On the flip side, I have suffered many agonies with Evolution. After every few days Evolution would download all the messages in my POP account again and mark them as unread. The re-downloading thingy has strained my bandwidth several times. Sometimes the password prompt for the email accounts would appear for no reason I could ever imagine. Any password I typed in those prompts would always return an error message followed by another two prompts to type in the password. I swear I had typed the correct password. Oh my, Evolution was supposed to remember my passwords as per my saved preferences. The "summary mismatch" error message is another frequent troublemaker. After restarting the application few times it seemed to correct itself somehow.
