It’s sending e-mail every hour, but I changed to sleep for a day, but  
keep send the e-mail by hour. I don’t know what to do to send daily.  
Could somebody help me?

thanks

I certainly would not use a long running daemon for this purpose. You  
should look into using cron and script/runner to execute the task daily.

0 8 \* \* \* /path/to/rails/app/script/runner -e production  
“Notifier.deliver\_report\_daily”

This will deliver your daily report each day at 8 am.

Best,

if you had initially set it to sending every hour and then changed it  
to every day in between, then u may have to re-start the daemon… did  
you do that?  
but i second Michael… you should be using a cron for this.

Use the delayed\_job plugin if you find it hard to tweak scripts to  
your taste.

Yes, I restart, but nothing change. Continuing send the old e-mail.  
Send one time the new, but after every hour send the old.

Do you know what I have to do?  
Thanks
