Introduced Safer SMTP Alternative: Added `SMTP_SSL`

[fazledyn-or]

Details

While triaging your project, our bug fixing tool generated the following message(s)-

In file: mail.py, method: send_email, a clear-text protocol such as FTP, Telnet or SMTP is used. These protocols transfer data without any encryption, which expose applications to a large range of risks. iCR suggested that data should be transferred over only secure transport channels.

Changes

• Added SMTP_SSL in send_email method with authentication
• Removed FIXME tag for SMTP
