In Gmail, is Automatic Forwarding completely safe, or, does it allow the target account to which the emails are forwarded, to send a reply somehow using the original recipient account's email address, and, are there any other dangers ?

• For Example - 'Account-One'( A Gmail Account ), receives an email, and because Automatic Forwarding for all email is set On, it is forwarded to 'Account-Two'( A Gmail Account ) which then replies to it ( to the very original sender of the email ), and, the very original sender of the email receives the reply which shows that the reply has been sent from 'Account-One'( A Gmail Account ) .

• I feel very stupid posting this question, but after some years of occasional searching on the internet, I cannot confirm that the obvious answer would be no.

• Could there be any other unknown dangers from setting Automatic-Forwarding On from a Gmail account to another Gmail account, or from a Gmail account to a Non Gmail account ?

• The reason I would want to do this, is because I have a primary Gmail account ('Account-One'), which I only use from a SIM card, and I also have a secondary Gmail account('Account-Two') which I use from a very very public WIFI network, so there is a greater chance of 'Account-Two' being hacked .
