If a Server is heavily loaded, it can contain thousands of message files in its Queue directory. Many operating and file systems cannot efficiently process large directories. You may want to split the Queue directory into several subdirectories, each containing a portion of Temporary and Queue files.
You may want to limit the total number of messages in the CommuniGate Pro Queue. When this number is reached, the modules reject attempts to submit new messages.
Use the WebAdmin Interface to specify the Queue processing options. Open the Mail pages in the Settings realm, then open the Queue page:
Queue Limit: If you specify a limit with this option, the CommuniGate Pro modules (SMTP, PIPE, RPOP, MAPI, WebUser) will stop accepting new messages when the number of messages in the Queue exceeds the specified limit.
Queue Foldering: This setting specifies where the CommuniGate Pro Server will create new Temporary files, and, as a result, how the message files will be stored in the Queue Directory. If you select the 0 (zero) value, no subdirectory will be created in the Queue directory, and all Temporary files will be created directly in the Queue directory. If you select the 10 or 100 value, subdirectory with NN names (where NN is a 2-digit number from 00 to 99) will be created in the Queue directory. The newly created Temporary files will be created inside these subdirectories. The server will use 10 or 100 subdirectories, depending on this setting value. If you select the Auto value, Queue subdirectories will be used when the total number of messages in the Queue exceeds 5000.
