I have a yahoo email account and a mac email accout that I get through Thunderbird. I get both of my Yahoo and Mac emails using Thunderbird in my PC. I have set up my Eris to receive my Yahoo and Mac emails. But for some reason, when I delete my Mac email from my Eris, it is also deleted from Thunderbird AND from my Mac server. Does anyone here use Thunderbird as their email application, and does your deleted email disappear from the server too? Thanks for any feedback.
