Version: (using KDE 4.4.2) OS: Linux Installed from: Compiled From Sources Every time I check my email in kmail (using a lotus domino imap server), kmail stalls at 20% for a few minutes, and then finally finishes. This doesn't happen to me with other imap clients such as thunderbird.
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
