This problem has been fixed. Unfortunately, there will be a hole in the archives unless someone happens to have a decent mbox archives for backfill (maybe one of the 3rd party mail archives have mbox archives available).

I'm getting backups of my last weeks' mail now, roughly in STMP stream format as far as I can tell. Will send it later. Need to filter out the openldap messages and check that I got it right first.
