I originally set up TBird to download my mail from my 1 email address & to delete that mail from the host server as it moved it into TBird. I recently had to set up a 2nd email address with Google. I now need to have TBird download that Gmail, as well as the 1st email address. However, I do not want both addresses mixed in the same inbox, & I do NOT want TBird to delete the Gmail from the Google server as it downloads. I'm low tech, so I'd appreciate some help with step by step instructions.
