Configuring Postfix


I use the panel centos Web Panel and from here it my create my certificate let’s encryt so I have my files

Installing full chain to /etc/pki/tls/certs/myhostname.cert
Installing full chain to /etc/pki/tls/private/myhostname.key
Installing full chain to /etc/pki/tls/certs/myhostname.bundle

and my myhostname.bundle file is empty is it normal?

So I set up my postfix file:

smtpd_tls_key_file = /etc/pki/tls/private/myhostname.key
smtpd_tls_cert_file = /etc/pki/tls/certs/myhostname.cert

and I had a problem receiving emails with several errors, and I received no email.

I have rewrite the file and I record this:

smtpd_tls_key_file = /etc/pki/tls/private/myhostname.key
smtpd_tls_cert_file = /root/

it works I receive emails well now. I do not understand why I had to get the fullchain.cer I had not put the .bundle file instead? If yes it is empty this file :frowning:

sorry for my english I’m french

Thank you
