I have an automysqlbackup.sh script that backs up and sends the database via cron. The script uses mutt to send the compressed file as attachment. I am on a shared hosting server.
It looks like mutt creates a temporary file named 'sent' in my home directory with all the headers and encoded attachment, and then fails to delete it. This file keeps growing with each attachment sent. I can't find any reference to this file in mutt's manual, according to the man page, mutt temporary files look like muttXXXXX.
Other than deleting the file manually, what are my options?
