After you have performed the necessary configuration to enable an MTA’s server to allow DNS lookups (see Section 3.5, Configuring the MTA’s Server for DNS Lookups), you must configure the MTA to perform DNS lookups.
By default, your GroupWise system is configured not to allow MTAs to perform DNS lookups. You can retain the system default of no DNS lookups, then enable DNS lookups for individual MTAs. Or you can enable DNS lookups for all MTAs in your GroupWise system, then selectively disable DNS lookups for individual MTAs.
To configure your GroupWise system so all MTAs perform DNS lookups (provided their servers are enabled for DNS lookups):
If you’ve used the GroupWise System Preferences to enable all MTAs to perform DNS lookups in order to send messages directly to other GroupWise systems (see Enabling DNS Lookups for All MTAs), you can disable DNS lookups for individual MTAs.
If you haven’t used the GroupWise System Preferences to enable all MTAs to perform DNS lookups, you can enable DNS lookups for individual MTAs.
