fixed correct processing of mails with data lines longer 4096 chars Mail messages with lines longer than 4096 chars were already read correctly, i.e. the spool files were correct. This commit fixes the reading of spool files with long lines. The old behavior was that the message body was truncated right before the first line longer 4096 chars. The number comes from MAX_DATALINE.
