A NetBSD server runs Postfix. The admin adds an alias `info: bob` to the aliases file and runs `postalias /etc/aliases`. Later, the admin checks the mail queue with `postqueue -p` and sees a message for `info@example.com` that is stuck. What is the most likely reason the alias is not working?

The alias file must be owned by the postfix user to be read.

The admin should have run `newaliases` instead of `postalias`.

The alias was added to the wrong aliases file that Postfix is not configured to use.

The admin did not run `postfix reload` after adding the alias.

Which command can be used to identify the active MTA process on a BSD system?

ps aux | grep -E 'sendmail|postfix'
