You might have experienced difficulties sending emails from more than one location (e.g. at home, at work, staying in a hotel, visiting another city or country). This is because the SMTP server assigned to you by your Internet Service Provider only works when you're connected to the Internet through that Internet Service Provider. This is a security measure used by Internet Service Providers to prevent people sending spam through their servers. MySendMail allows to send emails using a login and password from every internet connection without change SMTP server settings.
