Defragmentation-channel-specific option: MAX_PARTS (10 <= integer <= 100,000)
New in Messaging Server 7.4-18.01, the defragmentation channel supports, (in addition to the usual channel options), one defragmentation-channel-specific option, MAX_PARTS. MAX_PARTS specifies the maximum number of fragments a message can be broken into and still be reassembled. The maximum is 100,000; the minimum is 10; the default is 1000.
This defragmentation-channel-specific option would be set in legacy configuration in a channel-specific option file,
IMTA_TABLE:defragment_option, or in Unified Configuration is set under the channel's
options option. For instance:
msconfig> set channel:defragment.options.MAX_PARTS 500
Note that in Unified Configuration such channel-specific options are not (currently) schema checked: be careful when setting them as
msconfig will not warn of invalid values or syntax as it would for regular channel options! (Nor will
msconfig show whether or not such channel-specific options have any default value.)
In legacy configuration, where an option file is used, such an option file must be named
defragment_option, and stored in the MTA table directory.
