-HELO command specifies that a custom HELO greeting text will be used upon initiating client / SMTP connection session. If -HELO command is not used, the computer name is used by Command line email software when connecting to SMTP server.
febootimail -HELO mailer.example.org
febootimail -HELO "John-PC.corp.lan"
C:\>febootimail -SERVER smtp.server.com -FROM email@example.com -TO firstname.lastname@example.org -TEXT Sending email with custom helo message from command line mailer -HELO "client.email.lan"
The command line mailer client uses HELO command to identify itself upon connecting to SMTP server. HELO command is sent to SMTP server right after it responds to mailer connection with code 220 which indicates that SMTP service is ready.
