[HOWTO] Install mailcow in a LXC container on Proxmox 6.4-13 for home usage

I am aware that Mailcow team doesn’t provide support and advise to use LXC container to run a mailcow dockerized version. But accept community usage without...

It won’t. No problem to write a cron job.

Some other questions are popping up:

In the doc I read: "Die mailcow Daten (wie bspw. E-Mails, Userdaten etc.) werden in Docker-Volumes aufbewahrt - geben Sie gut auf diese Volumes acht:

clamd-db-vol-1
crypt-vol-1
mysql-socket-vol-1
mysql-vol-1
postfix-vol-1
redis-vol-1
rspamd-vol-1
sogo-userdata-backup-vol-1
sogo-web-vol-1
solr-vol-1
vmail-index-vol-1
vmail-vol-1

"
O.k. Got it. Are those volumes covered within the backup-script?

While I’m migrating from another email-server, is it possible to upload bulk white/black lists?

Hi
Really its not needed to prepare Proxmox host form MailCow LXC?

KrisFromFuture prepare Proxmox host form MailCow LXC?

LXC is not supported:
https://docs.mailcow.email/getstarted/prerequisite-system/

“Do not try to install mailcow on a Synology/QNAP device (any NAS), OpenVZ, LXC or other container platforms.”

Thanks for reply.

Is Proxmox VM with Debian 12 (not LXC) option ok ?

KrisFromFuture Is Proxmox VM with Debian 12 (not LXC) option ok ?

I would recommend that. Use a Debian 12 VM with Docker installed as per mailcow documentation.

I struggled for a long time, but eventually, I succeeded. It’s probably because I lacked knowledge. In the end, everything has been working fine for six months, thanks to the guys, everything is okay.

I used LXC+Docker

So without any changes in Proxmox Host ?
im trying to avoid modify Proxmox host

Sorry. I didnt feedback.In my case, it’s a corrupted container. There is a link in our community

The Topikstarter has described everything well. I can hardly help you anymore. This is the only disadvantage of linux, that when you set everything up, it just works)

If I remember correctly, there were nuances of docker with IPtables.

Hi all,

Just to be clear, LXC is not supported but works until now very well, since years !
Not use it for professional usage for sure, but for my personal use, 10 mailbox on a little memory server,
LXC works with what at say earlier.

But for sure, if you have a issue, you will not have any support from the mailcow staff.
If you can have a full KVM, is the preferred installation !

kicou Can you please share your process to get it up and running? Thanks.

kicou

Yes sure.

Follow the initial HOWTO without the step 1 “Prepare your proxmox hypervisor”.

It works like a charmn, without any preparation on the new Proxmox (Overlay and Naufs).

Lest Test from scratch on version 8.0.3 of Proxmox for me.
