SO, for the tim ebeing I have set that tag to undef so the tag is no longer added. But I also wanted to repair the messages that already ended up in dovecot 2.0

But now my mail client is experiencing problems with the messages (cannot display) and I think I've been to simplistic. I have for instance notedthat th esizeof the message is part of the filename. So, I can change these of course, but probably I need to change more.

I think your best bet is to delete dovecot.index* and run dovecot index -u username. Or revert all your changes. Depending what mail store you are using, this might lose any flags on your mails, such as \Read.
