I want to try the intelligent filter but have problems to bring it to work.
Maybe cause it binds postfix to localhost?

Did you configure all incoming mail to go to PMG first instead of your original email server?
 
Yes,

i have run PMG on KVM for a serval Days without problems. So i wanted tu try it with LXC. Its easyer to handle.
So MX Record is showing on the PMG server. But no incomming mail.

Every Email-Client says Connection Timeout.
 
Can you successful reached your PMG container via telnet from your internal and external network?

Click to expand...
that sounds like a very likely reason!

did you configure the LXC with a static ip? (it currently won't work with dhcp provided addresses)

please try to run:
* pmgconfig sync --restart 1
* systemctl restart postfix

and check the output of `ss -tlnp`
 
When i do pmgconfig sync --restart 1:

output of ss -tlnp seems correct:

I don't use a DHCP Server. It is a public static ip given.

those messages are harmless - they happen because you ran the command while your working directory is '/root' - try:
`cd / && pmgconfig sync --restart 1`

ss output looks good!

if it's still not working - I would guess that there is a problem with the networking:
* maybe a firewall is in place which drops connections to port 25/26 on your pmg , the hypervisor runs on, the switch the hypervisor is connected to, somewhere else in your network?
* try connecting from outside your network to port 25 on your PMG: `nc -v <PMG-ip-address> 25` - does this work?
 
seriously, i don't know what happened BUT now ist works?

What does pmgconfig sync --restart 1 do, that it works after it?
I installed pmg in a lxc container and have my configuration done.

Glad to hear!

Among other things it renders the configuration files for postfix (and clamav, spamassassin and postgresql) to work with your configured settings
(see https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmgconfig_template_engine).

It works after rendering the files and restarting postfix, because we had a small bug (fixed today) in the service file which runs during boot, which causes postfix to start with the unmodified stock config (hence the listening on 127.0.0.1) - see https://pve.proxmox.com/pipermail/pmg-devel/2020-April/001138.html

I think we'll publish an updated pmg container template soon - then this should work out of the box, without any commands!

Thanks for the report!
