Every week?  Unless you're using a telephone modem, an out of control mail
loop or being the victim of a joe-job can consume 5Gb of space in no time.
I recommend a more frequent interval if you're in the single digit Gb's.

If free space dips below 1Gb, (e.g. 900M), this will either fail
or do the opposite of what you want.  Maybe

 	MAILSPACE=$( df -k | awk '/\/dev\/sdd/{print int($4/(1024*1024)}' )
