To troubleshoot email sending issues, use the command line argument DEBUG or DEBUGX (detailed mode). The debug mode allows viewing Febooti Command Line Email internal variables, and client-server responses (SMTP or ESMTP).
Debug
Debugging of email sending process:
febootimail -FROM ed@example.net -TO ryan@example.com -DEBUGX -TEXT "Command Line Email and server debug mode." -SUBJ Debugging -SMTP smtp.example.comExample of the Debug mode console output using DEBUGX argument. Note that the SMTP server responses provided in this example may differ from the responses in your situation depending on a server software and a configuration. Also, the advanced debug argument DEBUGX still should provide the most comprehensive report on SMTP communication.
