Version: 1.11.0 (using 4.2.00 (KDE 4.2.0), Kubuntu packages) Compiler: cc OS: Linux (i686) release 2.6.27-11-generic No changes in my Kmail from KDE 4.2 Beta2, and then RC1. 4.2 final really seemed to have a bug that causes Kmail to hang like a dog, eating up as much CPU as possible while collecting from a POP account.
It also happens with imap accounts. *** This bug has been marked as a duplicate of bug 185818 ***
