Mail restore fails with address in use error

[stephdl]

Steps to reproduce

• Install a ns8 server
• Install the ldap account provider and configure it
• install mail server and configure it
• configure the backup to a repository
• do the backup to the repository
• restore the mail server and replace the existing mail server (mail1 is overwritten by another rmodule_id)

Expected behavior

I expect the restoration is fully workable

Actual behavior

The rspamd or the dovecot container could be broken, either fully stopped or the systemd service could be started but without tcp ports bound to the container.

a full restart of the dovecot and the rspamd container fix the issue

we can find in logs this kind of traces

it seems that we could start the new mail module before to have stopped the old one

I think we start the services of the new mail module before to remove completely the older one

evidence

• log of mail14 https://gist.github.com/stephdl/8b70a22552aedbf91d1c89e5f70670b0

• log of mail15 https://gist.github.com/stephdl/8c56df2a44f9d0df939462e0c88339c4

for me we start to remove mail14 at Feb 06 17:02:52

but we start services of mail15 at Feb 06 17:02:43

let's close for now, it will concern all modules with a fixed port like samba AD, ejabberd, the fix is in the backup process
