Run in verbose mode

All versions

The -v command-line switch tells sendmail to run in verbose mode. In that mode, sendmail prints a blow-by-blow description of all the steps it takes in delivering a mail message.

After the sendmail.cf file is parsed and after the command-line arguments have been processed , sendmail checks to see whether it is in verbose mode. If it is, it sets the HoldExpensive option (HoldExpensive) to false and sets the DeliveryMode option (DeliveryMode) to interactive.

The -v switch is most useful for watching SMTP mail being sent and for producing expanded output when viewing the queue.
