different SMTP with main account

My problem goes with my traveling. I have to use company emails for communicating with clients, but company SMTP is sometimes blocked by hotel net policy etc. With my previous email client, I solved it by using different SMTP server with a different e-mail address (mainly my Google e-mail address). My problem with eM Client is, that yes I can use different personal SMTP login and server and password, but it appears, that mail is NOT sent as my company e-mail but as my google private email (that one which I have set as SMTP) … any way to fix this?
