Dan,

Yes they are on the master. The master is not configured as a slave:

mysql> show slave status;
Empty set (0.07 sec)

mysql> show master status;
+------------------+----------+--------------+------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql_bin.000346 | 14862859 |              |                  |
+------------------+----------+--------------+------------------+
1 row in set (0.00 sec)

The relay-bin files contents are four characters:

pbin

They reside in the data directory. There is also a corresponding file:

MAILCD3-relay-bin.index

In this instance, MAILCD3 is the name of the server. There are least 346
of the relay-bin files.
