To recap:
I see this too. So far only with thunderbird. Do you Marten see it with 
other clients too ?

The bug is really strange since everything I can log/see about the 
conversion between dovecot and tbird suggests tbird has the bug.
BUT when I run tbird with other pop3 server it works.

The error triggered is that tbird tries to download an already deleted 
message (infact it just deleted it). And if I restart tbird it will start 
download at the last deleted message (error again).

I think our only hope is Timo or possibly some tbird developer.

Cheers
Jens
