+2001-05-23  Alain Magloire
+
+	* mailbox/mbx_default.c (mailbox_create_default): Check
+	for URL in the mailbox name.
+	* mailbox/mime.c (_mimepart_body_read): Use stream_is_seekable()
+	to detect if the stream is POP for example and read 'til the end.
+	(mime_get_part): Reuse the stream the original stream flags on the
+	newly created message.
+	Fix and patches provided by Dave Inglis.
