Sorry but one more question, using Webrick where can I found the mail that I send and the one that I receive ?
Thanks,

No problem.
Webrick has also nothing to do with your mail functionality. It's just the web server which you use to access your website. Your mail is sent via the SMTP server you have set up in your configuration. It's somehow done in the background. If you send an email in Redmine it should pop up in your mailbox like every other newsletter does. Have you tested your sending functionality under the administration > settings > email notification tab?
The other way around there are scripts to fetch emails from an POP3 or IMAP server and after processing them create issues with the processed data. The email itself is discarded at the end, or in case of IMAP marked as read.
Regarding your Apache problem, I think you've missconfigured something. Here's a stackoverflow thread about Apache throwing 503s: https://stackoverflow.com/questions/683052/why-am-i-getting-an-apache-proxy-503-error
