Hey guys,

I'm still getting theses errors while fetching mails via imap:
Error: read(/home/vmail/.../mdbox/storage/m.7): FETCH BODY[] for mailbox
INBOX UID 1823 got too little data: 284572 vs 47173
Error: Corrupted index cache file
Broken virtual size for mail UID 1823

I tried to export them with doveadm fetch. this works fine and doesnt
create any errors at all at the loge file. Any further toughts here?
Timo maybe?
