Same thing happened using fgets() > before I started trying fread(). 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: <http://www.iletter.org.uk> for a practical example (you want v2, not v2). -- Cheers -- Tim
