Caches are built gradually during the normal course of operation with satisfactory system performance. If your system configuration is complex or your data sources are large, you can preload your directory caches to prevent mail from backing up in the system during the initial directory cache building process.
You must upload all your input files before you begin the preloading process. Each import file must be comprised of newline-separated email addresses and use ASCII or UTF8 encoding.
On the Preload Configuration and Status page, browse to the Input file you want to use to preload your cache.
This file must be comprised of newline-separated email addresses using either ASCII or UTF format.
In the Function field, select the function for which the uploaded file is used.
Cache preload is performed in a per-function basis and is supported for the following enabled and configured functions: quarantine address resolution, recipient validation, routing, and address resolution. For all functions except routing, a single input file is shared across all data sources that are enabled for that function. For routing, you must associate your data source input file or files with each routing function.
Continue to upload your files until you have uploaded all of the files you want to preload. You must upload the data source file for each function. If the list of email addresses is shared across functions, you must upload the same input file for each function.
When you have uploaded all the files, click Start Preload.
You can return to this page at anytime to check your status until the Control Center restarts. The Preload % Complete column shows updates for each function as the page is refreshed automatically. You can also manually refresh the status by clicking Refresh.
The preload status appears as follows:
The preloading process has begun but is not yet completed.
All files have been successfully loaded.
Cancel was initiated but not completed.
The file loading process has been stopped.
The file load process was unsuccessful.
You can return at anytime to check your status until the Control Center restarts. You can also consult the Control Center logs for additional information.
