Thanks, did not find this hint on the mailinglist yet. Will try (sooner or later) and keep you informed. > I guess you're using only LMTP to deliver mails?

I must admit, "a lot" was way too exaggerated ;) Around 10000 successful LMTP deliveries a day. Around 1 to 3 errors a day. But data corruption is something we can neither accept, nor explain to our customers, since indexes are very important with mdbox. Regards Daniel -- https://plus.google.com/103021802792276734820
