SUMMARY

MaxLanMailSize is an INI file option that can be used with EXTERNAL.EXE version 3.2.x. This option is used to restrict the size of messages that users can send to an external postoffice residing on the same local area network (LAN). This option does not affect $SYSTEM messages that are sent during the directory synchronization (Dir-Sync) process.

MORE INFORMATION

It is possible to limit the size of the address updates that the postoffice receives from the Dir-Sync server by selecting Config, DirSync, Requestor, Options, Limit in the Administrator's program (ADMIN.EXE).

When a Dir-Sync requestor requests address updates from the Dir-Sync server, the server compares this limit against the update response that it is preparing to send. If the update response exceeds this limit, pacing is used.

Pacing is a process where the Dir-Sync server sends the global address updates only until the limit is reached. The remaining updates are sent by the Dir-Sync server in subsequent response messages. This is used to spread the propagation of large numbers of address updates over several synchronization cycles.

When a Dir-Sync requestor requests a complete Import (Config, DirSync, Requestor, Import), this limit cannot be used to pace the response. A manual Import must be performed. For additional information, please see the following article in the Microsoft Knowledge Base:

119450 Err Msg: Fatal 118 Transaction Limit Reached

The MaxLanMailSize option for External can be found on pages 252 and 253 of the Microsoft Mail "Administrator's Guide."
