The lock file name must be the mailbox file name followed by ".lock". Hence, the lock file name must be $HOME/mbox.lock if the mailbox file name is $HOME/mbox. In the configuration that you had, procmail was not locking against imapd or, for that matter, against any other program reading traditional UNIX format mailbox files. What you experienced was exactly what would be expected. Fixing the lock file definition should remedy the problem that you are experiencing. However, if you are not absolutely certain that you understand all details about mailbox file locking, I strongly recommend that you deliver to the spool directory (and leave procmail in default configuration) and let imapd move the messages to the mbox file. The defaults, although not particularly high-performing, were designed to be "safe", especially for systems on which the system manager is not an expert. An expert can certainly set up a higher-performing configuration, but doing so is very dangerous and should be left to experts. -- Mark -- http://staff.washington.edu/mrc Science does not emerge from voting, party politics, or public debate.
