Where I work, I am occasionally on call. My employer uses gmail. I have filters set up to forward selected messages to my android phone. When I receive the message, it can be from multiple addresses, such as addr1@ABC.com or addr2@ABC.com, (about 6 in total). So I know this is a business call instead of a personal call, I have multople contacts set up on my android phone and a distrinctive ringtone associated with these contacts. This is a bit cumbersome, as if there is a new email address, I need to configure a new contact.
I thought I could simplify by using an intermediate email account to change the sender name, ie: employer > intermediate > android phone, but this just seems to pass thru the original email address. Is there a way on an intermediate account to thange the "from" address, so my android phone receives email from firstname.lastname@example.org. This would simplify my contact management to one contact. The intermediate account I tried is gmail, but I do not care who is the intermediate is. Just looking for a solution
