The 'RFC2822MessageID' setting will prevent Mail routing from compliance
with RFC 2822.
Beginning with Domino 6.0.4 and 6.5.2, the Mail router enforces the RFC
2822 rule that each Message ID is unique at all times. In prior versions
of Domino, mail delivery failure reports had the same Message ID as the
original mail. If RFC2822MessageID=0 in the NOTES.INI, then Domino reverts
back to the old behavior prior to R6.0.4.
The parameter was added to allow customers to revert to old behavior.
When this setting is absent then Domino will ensure that all mail messages
have unique IDs.
Remove this setting from all NOTES.INI files. Using this parameter set
to zero would result in mail delivery reports being noncompliant with RFC
This setting exists in Domino 6.0.4 and 6.5.2 and beyond.
No restart necessary. Force the configuration change to be noticed by the
router via the following server console command:
tell router update config
