sendmail, 4th Edition

Options That Are Safe

Security considerations normally require that sendmail give up any special privileges for most command-line options specified by the ordinary user. But the ordinary user can specify a few options that allow sendmail to keep its special privilege. Those options are called “safe” and are shown in Table 24-2.
