Go to www.softhome.net and open a pop3-account. Then you can use their SMTP server as well. It's free. Maybe yoy can use it without appltying as well. Whjo knows? The address is mail.softhome.net.

Some ISPs block the SMTP port to prevent spamming. A workaround to this is to use port 25000 instead of 25. Apply :25000 at the end of the address like this: mail.softhome.net:25000. In some email-clients there will be other ways to choose port. In outlook you can choose it somewhere in the settings.
