Hi,
such´mal in der Admin-Hilfe nach "multiple mailbox"; da findest Du u.a. folgendes:
When a server sends and receives mail, server processes, such as the Router, access the server's MAIL.BOX database, writing messages to it and reading messages from it. Because only one process at a time can access MAIL.BOX, when mail traffic is heavy, access conflicts occur as multiple processes try to access the database simultaneously.
For servers that support a small number of users, access conflicts are rare, and the default of a single MAIL.BOX usually provides an acceptable level of service. However, on servers that support a higher numbers of users, creating an additional MAIL.BOX database can eliminate most access conflicts.
Grüße
Helmut
