Version: 1.10.3 (using 4.1.3 (KDE 4.1.3) "release 61.1", KDE:KDE4:Factory:Desktop / openSUSE_11.0) Compiler: gcc OS: Linux (x86_64) release 2.6.25.18-0.2-default Hi. Today I've attempted to configure Kmail from KDE 4.1.3 to point at my company's Exchange server using normal IMAP mode. The configuration went like a breeze, however any attempt to actually connect and download messages results in numerous error dialogs with "Too many open files" text. There is no way to close them and continue other than kill Kmail.
I can confirm this for kde4-kmail-4.2.0-86.9 (openSuSE 11.0) w/ the "KDE4 community maintained KDE 4.x / Qt 4.x packages (openSUSE_11.0_KDE4_Factory_Desktop)" repository subscribed.
I confirm this for kmail 4.2.1 on Gentoo using a Communigate IMAP server. You can workaround this if you use ulimit to increase the number of concurrently opened files. Unfortunately only root can do that, and you want to check your mail, not roots, so you have to mess about like this: xhost <name of your computer> su <root password> ulimit -n 100000 su <your name> export DISPLAY=<name of your computer> kmail
