Does anyone know how to automatically respond from the email, where i received mail from automatically. Because I forward my work email to my gmail, and i want to respond automatically without having to select my work email from there.Thanks! 
Gmail -- Respond from the correct email
gmail;email;google apps
Did you try the Reply from the same address the message was sent to option in you GMail settings?Go to Gmail settings > Accounts and Import. Under When receiving a message: select Reply from the same address the message was sent to.The works for me when I fetch the mail from IMAP or POP, but I haven't tested with forwarding. So it may not work.Good Luck
