Kmail's pakg-message states two parameters must be increased: sysctl net.local.stream.recvspace=65536 sysctl net.local.stream.sendspace=65536 Where do I put these so they occur each boot? I tried adding the following to /boot/loader.conf: net.local.stream.recvspace="65536" net.local.stream.sendspace="65536" But that didn't work.
