function SendmailTransport::__construct

Constructor.

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.
