[SOLVED] How can we reject emails that are not ldap users to Proxmox MG?

[sametileli]

Hello friends
I created the ldap settings to Proxmox. but I have a problem like this. I want users who are not in ldap to be denied. For example, a mail is coming, the mail address is contoso@contoso.com. There is no such user in ldap, but mail is accepted. How can I prevent this?

Put shortly you have 2 options:
* simply enable recipient verification (GUI->Configuration-> Mail Proxy->Options) - that way postfix will directly reject mails, which it could not send to your downstream servers (this only works if your downstream server answers with 5xx for an unknown address)
* create a fitting rule in the Rulesystem:
** one Who Object which matches : 'Unknown LDAP address, any profile)
** an action of BLOCK

I hope this helps!

I'll create a rule and ask to validate ldap users. I'll write the result tomorrow. thank you so much
