How to change postmaster email?

[lttabdul]

Hello all,

Firstly, this is the first time I use PMG I am not good with Postfix or the CLI. I would like to change the postmaster email from using the "postmaster@hostname.domain.com" to "postmaster@domain.com"

I tried to follow this guide but the commands did not work,

https://dhenandi.com/change-postmaster-address-to-domain-on-proxmox-mail-gateway/

When entering this command:

postconf | grep myorigin
append_at_myorigin = yes
myorigin = $myhostname

I get bash: append_at_myorigin = yes command not found


What is the method of doing it?

Thanks.

Follow as below.
Make sure your $mydomain is domain.com. To confirm double check your /etc/hosts.

How to change it? Proxmox Mail Gateway lock the configuration. You can’t edit directly your /etc/postfix/main.cf. It will be changed to default when you restart the services.


You need a template configuration for main.cf on /var/lib/pmg/templates/. Copy it to /etc/pmg/templates. But first, you need to create the directory.

mkdir -p /etc/pmg/templates
cp /var/lib/pmg/templates/main.cf.in /etc/pmg/templates/main.cf.in

And you can add this configuration to /etc/pmg/templates/main.cf.in. And restart the services

echo 'myorigin = $mydomain' >> /etc/pmg/templates/main.cf.in
pmgconfig sync


Well done, after this step. You did it. Try to trigger a mail to make notifications.

There is your issue: It's no bash command, it must be changed within the relevant config file Read the article with more care...

Thank you! Working. Is there a way to verify emails? I am using www.mailtester.com to verify emails.

Try Mail Proxy -> Options -> Verify Receivers
For my case, make sure you have meet the reject_nnknown_recipient_domain's requirement to work, which is missing MX record in my local DNS server.

No need CLI, just enable Verify Receivers in the webUI. Double check all valid email can come in as normal and non valid email is being blocked.

You can also read more about verify receivers on PMG https://forum.proxmox.com/threads/m...rify-receivers-and-greylisting.283/#post-1168

Do you mean all valid email able to receive and block all non valid email after enable verify receivers?

 

[lttabdul]

Do you mean all valid email able to receive and block all non valid email after enable verify receivers?

Yes. These are the settings still unable to verify emails..

Yes. How do I do it?

Never mind I have found out the solution.

It was to point the PMG IP as the relay and set it in relay.
