Alpine. But you are very low on the RAM. I will buy more RAM if I can (DDR2(?)).

Using it in an enterprise environment?

Does it have solid copper cores? If not, I will discard that cable and use new/another one.

Ohh, I didn’t know that.

But:

The key pair can be found in crypt-vol-1. Please don’t forget to backup this and other volumes.[1]

Yeah, first create domains and mailboxes.

Then you can find user’s Maildirs here for example:

/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data/DOMAIN/USERNAME/Maildir

If you done with the restore, remember to execute:

docker exec mailcowdockerized_dovecot-mailcow_1 chown -R vmail:vmail /var/vmail
docker exec mailcowdockerized_dovecot-mailcow_1 /usr/bin/doveadm quota recalc -A

Be very careful about the exit node. You may be involved with law enforcement. Your computer equipment may be confiscated.

Do you remember what brand of battery it was?

I think the original lasted longer than the replacement.

Maybe this is a combination of cheap battery and temperature. I feel the chassis is a bit warm.

Mains is very stable here, only very short breaks like fractions of a second. So no deep cycle.

Thanks!

Checkmk maybe?
