Google GMail Settings
The Google GMail service offers email client access for retrieving and sending emails through your Gmail account. However, for security reasons, GMail uses POP3 over an SSL connection, so make sure your email client supports encrypted SSL connections.
Google Gmail Incoming Mail Server (POP3) - pop.gmail.com (SSL enabled, port 995)
Outgoing Mail Server - use the SMTP mail server address provided by your local ISP or smtp.gmail.com (SSL enabled, port 465)
