Thought I would just jump in. Dovecot has "single instance attachment storage" (SIS) as well as its own native mdbox binary format (multiple emails per file indexed efficiently). The SIS is a feature that I am really excited about since we have multiple user receiveing the same email - it really saves on storage space.

Cheap US$5 cloud instances are super attractive propositions for spammers who have absolutely abused these providers and made it difficult for legitimate senders to host on them.

[OT] Requesting feedback for VPS/Cloud for email (MX) server?
Hi, I want to host my own email on the cloud - I don't want to use G Suite or any other commercial service because I would like to have control over my email. I read around a little and it seems that most cloud providers block SMTP ports (25,587,465) from/t the internet as well sometimes from within their network. This poses a real problem for my deployment plans. Also, note that my design has separate MSA (submission), Mailstore (IMAP) and MTA (MX) nodes. I have shortlisted Digital Ocean and Linode for my use because both of datacenters in India. Is anyone using either of them for MX service? Any and all feedback is most welcome including specialist/small VPS providers who I can consider to host the MX node for my domain at least. Kind regards, Didar -- Fortune finishes the great quotations, #6 "But, soft! What light through yonder window breaks?" It's nothing, honey. Go back to sleep.

systemd-nspawn networking inside VirtualBox VM
Hi, TL;DR How to get systemd-nspawn containers networking so that they can talk to each other, the host and the internet inside a Buster VM? VirtualBox on Windows 10 which has internet connectivity via a wireless interface. I am running a Buster VM with hand picked minimal packages, networking is configured simply using interfaces(5) file with DHCP. I have configured a "NatNetwork" on VirtualBox which allows the VMs to connect to each other and the internet. I was wondering if I can do similar thing with containers inside the buster VM. I used `debbootstrap' to have a template directory of buster under "/opt/templates/buster". I then simply copy the directory tree over to "/var/lib/machines". I tried a few networking options of `systemd-nspawn', but since I am not well educated about macvlan, ipvlan, I could not get the networking working at all. I would like to avoid using "systemd-networkd/systemd-resolvd" especially on the Buster host - using those it seems should make everything work automagically. If it works then I will be able to test my Dovecot/Exim setup easily in such throwaway containers. I currently do testing using VMs. Does anyone have experience in having this kind of scenario working? Regards, Didar -- Baby On Board.

I have been using XFS for data on dual HDD (RAID1->LVM->LUKS->XFS) on Debian Stretch for more than a year, haven't experienced issues yet. OS is on Ext4 on SDD.

Debian Perl or Brew Perl for production application?
Hi, I am developing a perl application to be deployed on a production Debian Stable VM. So far, my approach has been to use the debian perl packages (perl modules) and stay within those facilities. I am the sole system operator and wannabe developer, there are no teams of sysadmins or developers. Do you guys who run production debian stable servers use the debian perl packages or use something like PerlBrew? I asked this question on #perl IRC and they answered "PerlBrew/plenv/perl-build" - I want some experienced opinions from the debian community as well. Regards, Didar -- All international orders must be accompanied by payment in U. S. funds.

How to automate away partition prompt in preseeded Jessie auto-intall?
Hi, I'm trying preseeded installation with the Jessie netinst CD ISO. Everything seems to work fine, except one prompt that still stalls until manual confirmation for the drive to erase/format/use for target installation. My preseed file and the screenshot of the dailog prompt can be found at the following URL: https://drive.google.com/open?id=0B9-tBo8X88GLfllQZURQQ3NyMTkzUzlHRDFYc1hVeGlVZU5iQWpodFIzVkxwTkF6YXc5TGM Details: * Installation is being done inside a KVM instance on my laptop. * Network is provided by VDE (Virtual Distributed Ethernet) * Preseed file is being served via a python SimpleHTTPServer invocation * KVM instances can access both the host (hypervisor) and the internet KVM invocation: (single command line) kvm -drive file=debian-8.1.0-amd64-netinst.iso,media=cdrom -drive if=virtio,file=test-install.qcow2,media=disk -netdev vde,id=net0 -device virtio-net,mac=52:54:00:12:13:15,netdev=net0 -m 256 -boot once=d Here are the lines relevant to the partitioning portion from the preseed # Partitioning d-i partman-auto/init_automatically_partition select biggest_free # Still prompts for confirmation even after specifying d-i partman-auto/disk string /dev/vda # Also tried with /dev/sda (with KVM IDE interface emulation) # A total shot in the dark, obviously didn't work #d-i partman-auto/confirm boolean true d-i partman-lvm/device_remove_lvm boolean true d-i partman-md/device_remove_md boolean true d-i partman-lvm/confirm boolean true d-i partman-lvm/confirm_nooverwrite boolean true d-i partman-auto/choose_recipe select atomic d-i partman-partitioning/confirm_write_new_label boolean true d-i partman/choose_partition select finish d-i partman/confirm boolean true d-i partman/confirm_nooverwrite boolean true d-i partman-md/confirm boolean true d-i partman-partitioning/confirm_write_new_label boolean true d-i partman/choose_partition select finish d-i partman/confirm boolean true d-i partman/confirm_nooverwrite boolean true This singular prompt is the only hitch in the completely automated installation.

Ok, it seems the only requirement was to set the PHP_INI values as in the
.htaccess file provided with the roundcube package.
I created the /var/lib/roundcube/.user.ini file with the following command -
# awk '/^php_/ {print $2, = ,$3}' /var/lib/roundcube/.htaccess
/var/lib/roundcube/.user.ini
This makes roundcube work. However, the .user.ini can only work for
PHP 5.3 and above
which is the case in Squeeze.

The situation occurs only when I pass -nographic option to vdekvm. I use `ssh' to remote login into the guest. The host OS is not Debian (Ubuntu 8.10) and the KVM version is quiet old - so, this might have probably been resolved by now. Of course, the workaround is to simply use snice/renice to change the priority of all the user processes upto the sshd instance; meaning to first renice the shell (bash) and then renice the sshd (as root).
