Why can't I send email?

This is likely because your ISP is blocking port 25. Many ISPs are now blocking traffic on port 25 not using their servers. You will have to contact your ISP and use the SMTP server provided by your ISP. You canchange in your email program the outgoing mail server port of 25 to port 587 and this should fix the problem.
