This section describes some recommendations for tuning your system to achieve and maintain optimal performance of distributed e-mail. Note that performance varies inevitably from case to case; therefore you should consider these values as a starting point only and experiment with the parameters listed to determine the values that best suit your configuration.

Note also that distributed e-mail is resource intensive. In addition to configuring the parameters described here, ensure that your database, network, and SMTP servers can handle the volume of traffic generated by distributed e-mail. It may be necessary to scale your hardware at each level of the targeted e-mail architecture to achieve the level of performance you require.
