sales email and copy_method copy

[bincani]

When sales emails are set to copy the to field of sales emails are populated with both the customers email and the copy to email address, so the customer sees the copy email. This doesn't happen all the time???

Current fix: switch to use bcc

select * from core_config_data where path like '%copy_method%';
update core_config_data set value = 'bcc' where path like '%copy_method%';
