Public bug reported: The `at` program uses the local mail in order to report errors, specifically, it requires the `sendmail` binary.
Without `sendmail`, any error during a job execution is reported in the syslog with a very confusing reference to a missing "mail" program. I suppose that error diagnosis is a requirement in job scheduling, therefore, the `sendmail` package should be required by the `at` package.
