In short: In Gmail, is there a way to let the "send from" address change automatically depending on which label the mail has?
In long: I have 4 accounts connected to Gmail.
Lets say golob@private1, golob@private2, golob@work1 and golob@work2.
Currently I'm using "Reply from the same address the message was sent to". But what, I want to have is the send from in reply would be based on the address the message came to (or based on a label), but it wouldn't necessary be the very same address.
So for e-mails sent to golob@private1, golob@private2, I want to reply with golob@private1 and for e-mails sent to golob@work1, golob@work2 I want to reply as golob@work1.
I know, I can install scripts for it, but I want it to be portable so that the solution would be base solely on Gmail options.
NOTE: The question is different and way more complex then In Gmail, can I base my "send from" address on a filter?
