Hi! I hope someone knows more about the issues I've encountered in: Setup: I am running dovecot 2.1.7 on Debian Wheezy in a virtual machine (kvm-style qemu-kvm: host: ubuntu 13.04/1.4.0-dfsg-1expubuntu). The mail storage is a directory on the host machine mounted via virtfs (9p2000.L) on the guest. Furthermore ISPConfig is involved in that setup, but that should not make any significant difference at that point. Problem resolved: The problem is, that similar to nfs mmap() and dotlocking seem to fail - the mmap issue could be resolved by adding: mmap_disable=yes to dovecot....

Hi, I'm almost give up again because for a day I try to access my windows kvm guest from FC20 :) I've tried everything including virtio mapping mount -t 9p -o trans=virtio,version=9p2000.L hostshare /tmp/hostfiles where I get the following messages mount: special device hostshare does not exist --- --- to be honest clipboard sharing would be enough for me, so I googled why it is not working and I applied this: https://mytechdepot.wordpress.com/2013/02/22/enabling-clipboard-cop...

I get a ton of these mmap() errors in the log. I noticed there's a double slash before Maildir. Is this normal? Config error? Dovecot bug? dovecot: imap(email at email.net): Error: mmap() failed with file /shares/email/vmail/vmail1/email.net/e/m/a/email-2017.02.25.08.09.39//Maildir/dovecot.index.cache: Invalid argument I'm running dovecot version 2.2.22 Thanks Eric
