What happens if you run it like this?
10 20 * * * root /usr/bin/perl /etc/database-backup 2>&1 | sendmail garbage
Cron uses /bin/sh to execute the script like this.
/bin/sh script
This will ignore whatever is on the first line the script, #!/usr/bin/perl,
and since it is not a valid bourne shell script it will most likely not work.
I based this on my interpretation of the following from the crontab(5) man
page, which means that I might be wrong.
The entire command portion of the line, up to a newline or % char-
acter, will be executed by /bin/sh or by the shell specified in the SHELL
variable of the cronfile.
