Well Ladies and Gents I have a one off here. Our main mail domanin is gasai.com, we recently entered into a business venture with another company and we have adjusted Exchange to receive email for lp.gasai.com. This all works just fine the problem is we have a user that primarily works as a gasai.com and his primary email address is gasai.com so when he sends a message out the replies are sent to gasai.com. So what happens if he needs to send email as lp.gasai.com? I tried adjusting the from and putting in his lp.gasai.com but resolves right back to the gasai.com address (His Primary)
I need an easy way to get him to be able to send mail as it where from lp.gasai.com when he needs to and not have it appear or reply to his gasai.com address. I could create another account and then his primary on that would be the lp.gasai.com address but I want to avoid that if possible.
So any suggestions ?
