SMTPOutputStreampublic class SMTPOutputStream extends CRLFOutputStream | In addition to converting lines into the canonical format,
i.e., terminating lines with the CRLF sequence, escapes the "."
by adding another "." to any "." that appears in the beginning
of a line. See RFC821 section 4.5.2. |

| Methods Summary |
|---|
| public void | ensureAtBOL()Ensure we're at the beginning of a line.
Write CRLF if not.
if (!atBOL)
super.writeln();
| | public void | flush()Override flush method in FilterOutputStream.
The MimeMessage writeTo method flushes its buffer at the end,
but we don't want to flush data out to the socket until we've
also written the terminating "\r\n.\r\n".
We buffer nothing so there's nothing to flush. We depend
on the fact that CRLFOutputStream also buffers nothing.
SMTPTransport will manually flush the socket before reading
the response.
// do nothing
| | public void | write(int b)
// if that last character was a newline, and the current
// character is ".", we always write out an extra ".".
if ((lastb == '\n" || lastb == '\r" || lastb == -1) && b == '.") {
out.write('.");
}
super.write(b);
| | public void | write(byte[] b, int off, int len)
int lastc = (lastb == -1) ? '\n" : lastb;
int start = off;
len += off;
for (int i = off; i < len; i++) {
if ((lastc == '\n" || lastc == '\r") && b[i] == '.") {
super.write(b, start, i - start);
out.write('.");
start = i;
}
lastc = b[i];
}
if ((len - start) > 0)
super.write(b, start, len - start);
