I can send you a copy of a complete broken mail folder including cyrus.cache, 
cyrus.cache.NEW, cyrus.header, cyrus.index, cyrus.index.NEW and mails. It's 
nothing secret. It's a subfolder of my mailbox where I put the mails from this 
mailing list in. I'll send it in a separate mail to your address.

Where can I check this?

If there is a change, we would stay at the version that comes with the 
distrubution, because then we can easily update on bugs or security issues 
through the repository. But if there's a bug, that could be fixed I, or 
whoever, can send it to redhat.
