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.
