How can I force fsck on next boot
You can force an automatic full check by changing the check interval using tune2fs (-c and/or -i).
-c max-mount-counts
Adjust the number of mounts after which the filesystem will be checked by e2fsck(8). If max-mount-counts is 0 or -1, the number of times the filesystem is mounted will be disregarded by e2fsck(8) and the kernel.
-i interval-between-checks[d|m|w]
Adjust the maximal time between two filesystem checks. No postfix or d result in days, m in months, and w in weeks. A value of zero will disable the time-dependent checking.
It is strongly recommended that either -c (mount-count-dependent) or -i (time-dependent) checking be enabled to force periodic full e2fsck(8) checking of the filesystem.
The above command would tell the init scripts to run fsck on hda2 at every boot.
# tune2fs -i 1d /dev/hda2
The above command would tell the init scripts to run fsck on hda2 after 1 day.
If you only want to run fsck on the next boot, please execute the following as the root user.
This will only run the file system check on the next reboot. By touching the file “forcefsck” in the / directory, it will force the system to perform a full file system check.
The file “forcefsck” will be deleted automatically after fsck is finished.

Changing Spamassassin to check emails larger than 250KB
Spamassassin by default will not check emails larger than 250 KB. This is limited to prevent spamassassin from generating a large load on the server.
If you would like to change this setting to a higher value you can edit the following file:
vi /usr/local/psa/bin/psa-spamc
and change this line to a higher value:
MAX_SIZE=256000 # max letter size to filter
Spamassassin will use the new value immediately with no need to restart any services.
