Hi,
I'm trying to use ar_mailer to send newsletters in my application. The thing is that what I've done works fine while I'm under development mode but when I try to run it in my server in production mode I become the following error(it also appears after switching webrick to run in production mode):

as I mentioned, while working in my machine, if I restart Webrick and
switch to production mode, it just stops working and when I switch back
to development mode, it works again…
