You need to rtrim() each input line, and stop when you find a line consisting of just a full-stop (.)
Also, use fgets() to get the lines. Much easier.
$message = '';
while (true)
{
$line = rtrim (fgets ($mail_sock);
if ($line=='.') break; // (Well, I think it's "break;" I should use to exit this loop :-)
$message .= $line;
}
I've had no problems doing this. See here:

for a practical example (you want v2, not v2).
