I can't send email because my ISP blocks SMTP (port 25)

Some ISPs block their customers from accessing other ISPs mail servers, in an attempt to stop spam originating from viruses on customers' PCs. If you need to get around this restriction, you can try using the secure connection option in your email client or changing the SMTP port from 25 to 26.
