Dear all, first of all I'd like to thank all of you for your work and your patience with all the silly questions (like mine below). As I've just said I've a problem in the set-up of a new computer. I've already installed Thunderbird in 3 different computer (2 win and 1 MAC) always with the same options, same email address and same identities. Yesterday I've bought a new PC and I've to set up Thunderbird also there. Everything goes fine but I'm not able to fix a small (but not stupid) problem. I'm using a gmail account where there are forwared different email from different email account (different work email). In all the other computer I'm able to reply to the email using the opportune identity automatically. In this new one is not possible and I've to select the identity manually. Looking around I've seen that sometimes it seems related to the specific info of the received email. However I've tried with all the other computers and when I try to reply to the same email they will directly use the identity, while the new one use the mail gmail account. Do you have any tips to solve this? Thanks a lot, Tommaso PS: I've seen that someone have solved this problem using a filter and creating specific folder for the emails but actually this will interfeere with my usual work and, more important, with all the other computer it works also without this shortcut.
