EB sender's E-mail - Hmailserver

Hi Team,

I wonder if you can help me here please. It is quite tricky.

I have been trying to change the display sender's E-mail address form the general  smtp user account ( setup on EB and Hmail server)to the specific user account of sender (account used to log on EB).

Basically if a user A sends and e-mail to B. User b should be able to see sender's A E-mail address instead of the generic  smtp account E-mail address set up to transfer E-mails between EB and Hmail server.

I am aware that I can query the sql server to get the information but the entry will obviously update the table only once the E-mail is sent;

Mail distributor: HMail server 

EB version (Director): 15.4.1.325

EB Web: version 6.2.1.325

Hmail server: 5.5.2-B2129

SQL 2008 R2

Thanks
