Hi, I have Thunderbird installed on two computers, with the same two IMAP accounts. On one computer, I have a bunch of message filters that sort incoming emails into folders. With IMAP, the same thing happens on the mail server – very convenient indeed. Now I would like to make the same filters on the other computer, but wonder if there might be a caveat if Thunderbird is running on both computers simultaneously. What if the two computers receive the same new email, and decide to move it to a different folder at the same time? Is there any risk of a conflict that will mess up the email, or the entire folder structure? I have not yet tried this, as I don't know ''if'' there is a risk. Anyone with insight on this?
