Problem Postfix connection with LDAP

Good morning,

for a problem with the certificate chain I’ve done the renewal of the entire chain using this article:

After the renewal, I’ve tried to create a mail alias for a user on web interface and give me back this error:

he LDAP object could not be saved: The domain part of the following mail addresses is not in list of configured mail domains

I’ve checked the mail.err log and i find this log:

postfix/trivial-rewrite[7594]: error: dict_ldap_connect: Unable to set STARTTLS: -11: Connect error

I’ve tried to re-done the entire chain of certificates but don’t correct the issue.

Someone had the same problem in the past?

Thank in advance, Manuel
