Дилян, ellie,
I can't speak for Tecnologia but I didn't do an in-place upgrade. I installed Cyrus 3.4.2 onto another server and replicated my messages onto that machine. I assumed that indexes and mailbox construction would be handled correctly using that method. Should I try running 'reconstruct -V max' to see if that clears things up? I did try 'reconstruct -M' on my mailbox and nothing changed. I even tried deleting my mailbox and recreating it and I'm still not able to see any messages using a mobile client.
ellie,
I think you may be right about the search indices being borked. I tried a server search on a "working" client and got back nothing. I'm going to start digging through the manpages and documentation for any search-related settings and see what I can find.
Thanks,
Chris
