Thunderbird, downloading multiple versions of the same email
I have recently started using a spam filter which works great at blocking spam and has no issues on my phone, tablet or webmail emails. However, since installing it, thunderbird has begun redownloading older messages from the server so that I mave multiple copies of the same emails (in some cases 3 or 4 and seems to add another each day).
Obviously, as it is only effecting thunderbird, I think the issue lies in the thunderbird settings but I cant seem to work out how to go about resolving it.
