I encountered a bug, that prevents me from moving mail and as a side effect it messes up all thunderbird/mozilla mail clients (they won't do any message copy/move until I restart them). .. Date: Tue, 15 May 2085 16:51:38 -0800
The error message says "Invalid internal date". I see two problems here:
Date: header isn't the same as internal date. Internal date is the date when the message was saved.
COPY command doesn't do anything special with Date: header. It especially doesn't try to put it to internal date field.
So it looks like when copying/moving a message Thunderbird goes and uploads the message with APPEND command and moves Date: header to INTERNALDATE. If it really does this, it's pretty bad behavior.
Anyway, it still is a Dovecot bug that it doesn't accept such internal dates. Fixed: http://hg.dovecot.org/dovecot-1.0/rev/2460c70d1ffb
