Crontab behavior in AMD64

[Francisco Reyes]

Is there a difference in the behavior of crontab in AMD64 vs i386?

I have a crontab
14 22 * * * /usr/home/hank/bin/tozoraida.sh

which is not running
When I try to research the problem the only thing I see is an error in 
maillog
postfix/sendmail[36590]: fatal:
   No recipient addresses found in message
   header

Have setup user crontab on several other machines without problems, but 
they were all i386.

Archives came up empty so don't know if this is an issue with the AMD64 
branch or something else.
