how store owner can reply email!

Hi guys, I met a problem about email reply: we want direct reply our customer's order email that means when buyer completed his order we will got confirmation email from opencart, but we can't reply this email( because this email come from our sales email), so, please help me solve this problem.
Current version 1.5.4
if we can under confirmation email reply our customer it will be more effective.
thanks

Hello

I think you can use this instruction to email a customer directly

Log into your OpenCart Dashboard
Go to Sales > Mail
The mail screen will appear. Fill in the fields by choosing the appropriate sender (From:), whether you’re sending this email to all customers, specific customer groups or only newsletter subscribers (To:), the subject (What the email is about), and the message (the actual email).
Click “Send”

additionally have a look at this mod

and

http://www.opencart.com/index.php?route ... %20&page=2

and
http://www.opencart.com/index.php?route ... e=0&page=4

and
http://www.opencart.com/index.php?route ... on_id=1959

and
http://www.opencart.com/index.php?route ... e=0&page=2

and

these mods are all free or low cost.

i suggested mods because most times those who create modules are working with opencart and will usually give some support and there is a good chance the method they put out is working for people or they can be approached directly for help.

maybe there is another remedy for your issue, but I hope i have helped someway

Thanks for your reply
actually, my boss want use mail system talk with customers. he do't want use opencart admin system.
directly use order confirmation email reply our customers, thet will be more easy.
