After googling around I found that the error appears to be coming from sqlite, and that sqlite sometimes uses a .db file extension for its databases. Furthermore, the problem only appeared to be associated with one of my email addresses. Therefore, I deleted the following file corresponding to the email address that was having trouble (portions of the following line have been changed to "xxx" for privacy):
rm ~/.evolution/mail/pop/x...@xxx.org@xxx.xxx.com:110/folders.db and after restarting Evolution, everything seemed to be fine again. -- Error receiving email "File is encrypted or is not a database" https://bugs.launchpad.net/bugs/604846 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
