Qpopper's Quota problem

Article Title: Qpopper's Quota problem. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
Qpopper is the Open Source POP3 Server of QUALCOMM. The latest version is 4.0. This software is widely used on Solaris. The problem I encountered in practical application is that after the user's email quota is exceeded, the system administrator must manually intervene to expand the quota to continue receiving emails.
The cause of this problem is that the POP server needs to create a temporary file, and the file system where the file is created is in the same file system as the spool directory in the user's mailbox.


For Qpopper, the solution is to separate the two file systems, specify the switch during compilation, or set the switch in the configuration file.

Note that/usr/mail is also attached to/var/mail in Solaris. Therefore, we need to delete/usr/mail to make the system normal.

The following provides an alarm program for the disk quota. Write crontab to monitor your user email usage.
