Which can be 8000 or more. qmail was just hard coded to accept 256. With the big concurrency patch it replaces that hard coding with 512. You'll probably need to increase the systems open file descriptor limit. With linux I do the following line before starting it up: echo 80000 > /proc/sys/fs/file-max && echo 80000 > /proc/sys/fs/inode-max You can also change the ext2 permissions on the /var/qmail/queue directory if you have it mounted as a separate partition, for example: /dev/sda6 /var/qmail/queue ext2 defaults,noatime 1 2 The noatime reduces disk I/O since it doesn't updated times for accesses. I'm not sure about this one. But it seems to be working okay for me. Ken Jones
