Due to security measures that have been implemented by some e-mail providers (such as gmail) you may need to modify the e-mail settings on your system. This would include adding the security port to the SMTP address and you may also have to download and install ActivePerl from Perl Software.
You can include the security port by adding it to the end of the SMTP address by appending a colon ":" and the port number. For Gmail, the TLS port is 587 while the SSL port is 465.
If TLS or SSL is required, you will also need to include the SMTP User name and password for the sending e-mail account.
