-SSL command enables SSL data encryption when connecting to SMTP server.
SSL is an acronym for Secure Socket Layer, a cryptographic protocol that ensures secure data transfer over the Internet. On contrary to unencrypted data transfer, SSL provides significant security benefits during authentication with mail server and data communication.
The default port for SSL connection is 465. Some servers provide both encrypted and non-encrypted access, and it is possible to choose between secure or plain connection.
C:\>febootimail -SERVER smtp.mailserver.com -FROM email@example.com -TO firstname.lastname@example.org -USER john -PASS 3kr5$DrB -MSG Email sent through secure server -SSL
Usually, SSL command is used with one of the SMTP server authentication methods using -AUTH, -USER and -PASS commands.
C:\>febootimail -SUBJECT Secure Gmail email -SERVER smtp.gmail.com -SSL -AUTH PLAIN -USER YourEmail@gmail.com -PASS *********** -FROM YourEmail@gmail.com -TO email@example.com -TEXT This email is sent via Gmail's server. It is easy and secured with SSL!
