• A. With any MTA, the sendmail command must be run periodically by the cron daemon.
• B. When using systemd, sendmail is an alias to relayctl.
• C. The sendmail command prints the MTA's queue history of which mails have been sent successfully.
• D. It is only available when the sendmail MTA is installed.
• E. All common MTAs, including Postfix and Exim, provide a sendmail command.

Correct answer: E
