Prevent Exim4 from using up all disk space on Debian, 6.03.2009 10:20
Adding the following line to the Exim4 configuration prevents that all the disk space is used up by the messages in the spool folder:
check_spool_space=100M
This refuses incoming messages with a "452 Space shortage, please try later" message when less than 100 megabytes of disk space are available on the partition where the spool folder resides.
