In lsrc.server.php I see the following starting on line 455:
if ($databasetype == 'odbc_mssql' || $databasetype == 'odbtp' || $databasetype == 'mssql_n')
{
$createtokentable.= "email C(320) ,\n "
."emailstatus C(300) DEFAULT 'OK',\n ";
}
else
{
$createtokentable.= "email X(320) ,\n "
."emailstatus X(300) DEFAULT 'OK',\n ";
}

This should set the default to 'OK'. I checked my database and the emailstatus field did not have a default value. When I attempted to set it, I got an error message stating that you cannot set a default value for a text/blob field.

I modified the emailStatus field to a varchar(255) and set the default value. Now, when I import tokens, the status is appropriately set to 'OK'.

Is there a reason that this field is text/blob rather than varchar?
