Do you have a mail server experiencing high iowait times?

  • increase your conf-split to a bigger prime number (I use 521)
  • reduce the number of incoming smtp connections by
    • improving your IP reputation and RBL filtering
    • load balancing your traffic across multiple servers
  • splitting the load across more disks or disk arrays
