Carsten, No, I do not count more than 50k msgs in our largest mailboxes but I'd also welcome information on metadata (cyrus.index and cyrus.cache files) operations on huge mailboxes. Is the I/O cost of message adding relative to O(n), n being the number of msgs already in the mailbox, or is it independent thereof ?
