The JournalLimitForwardToAdmins setting in NOTES.INI can limit the number
of copies of a message that gets journaled for a specific case:
It limits journaling of messages forwarded to administrators via the special
SMTP 'postmaster' or 'abuse' addresses.
Setting JournalLimitForwardToAdmins=1 will prevent this duplicate copy
of the forwarded message from being journaled.
The original message will still be journaled. This NOTES.INI setting must
be enabled on the same server which has journaling enabled, and which is
doing the forwarding.
Some customers may prefer to leave this option disabled thereby allowing
messages to be double journaled.
When this setting is absent or set to 0, the behavior is disabled.
Enable this setting on servers with journaling enabled to substantially
reduce the size of the journaling database.
