Are you sure it happens "every time"? How many times have you
upgraded popa3d on that server? What versions those were? What OS
and processor architecture?
The behavior you're describing is usually seen when the way message
unique IDs (as seen with the UIDL command) are calculated changes. I
was careful to not do such changes without reason. But I had to do it
once, between versions 0.5 and 0.5.1. So if you're upgrading from a
version older than 0.5.1 to 0.5.1 or newer, then your users will have
to re-download their mail stored on the server once. Any other popa3d
version upgrades shouldn't cause this behavior.
