What are maillock errors?
A maillock error indicates a failure to obtain exclusive access to the mail spool. The error number indicates the nature of the problem. More details are usually found in the log. Here are what the numbers mean: • The user name is too long • Qpopper was unable to create the dot-lockfile. Check the permissions on the spool directory, and also make sure the user is not over quota and the spool disk is not full. • Qpopper was unable to write its process ID into the lockfile. Check if the user is over quota or if the spool disk is full. • The spool was locked by another process; perhaps the delivery agent was adding new mail. If this persists, it indicates a problem. • Something else went wrong. Check the log for a more detailed error message. • Qpopper lost the lock in the middle of locking it. If this persists, it indicates a problem.
