-SSL switch enables SSL data encryption when connecting to SMTP server with SSL support.
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 which is also used unless specified otherwise. Also, while some servers provide both encrypted and non-encrypted access and it is possible to choose between secure or plain connection, other SMTP servers may accept only one of these options.
C:\>febootimail -SERVER smtp.mailserver.com -FROM firstname.lastname@example.org -TO email@example.com -USER john -PASS 3kr5$DrB -MSG email sent through SSL enabled SMTP server -SSL
Usually, but not necessarily, -SSL switch will have to be used with SSL enabled email SMTP server authentication (-AUTH, -USER and -PASS).
Example: sending Gmail email from DOS using SSL. Just replace YourEmail@gmail.com with valid Gmail address:
C:\>febootimail -SUBJECT Secure email from DOS with Gmail and SSL -SERVER smtp.gmail.com -SSL -AUTH PLAIN -USER YourEmail@gmail.com -PASS *********** -FROM YourEmail@gmail.com -TO firstname.lastname@example.org -TEXT This mail is sent from DOS using Gmail's server. It is easy and secured with SSL!
