* Supported modes are -bs and -t, with any additional flags desired.
*
* The recommended mode is "-bs" since it is interactive and failure notifications are hence possible.
* Note that the -t mode does not support error reporting and does not support Bcc properly (the Bcc headers are not removed).
*
* If using -t mode, you are strongly advised to include -oi or -i in the flags (like /usr/sbin/sendmail -oi -t)
*
* -f<sender> flag will be appended automatically if one is not present.
