    We have a running multi server environment. Now we add 2 new mail servers only for forwarding/receiving emails from clients with their own exchange servers. I add the to servers (mx1 and mx2), the domain and the destination (transport) IP to the e-Mail routing. The test mail failed and I found this error:
    mx1 postfix/proxymap[1161540]: warning: connect to mysql server 127.0.0.1: SSL connection error: SSL_CTX_set_default_verify_paths failed

    Why tried postfix to lookup the domain from the local mysql server and not from the main database? The sol connection between the main server and all the other servers (ns, database..) a secure with SSL.

    Any idea?

    Don't add a mail domain when you want to forward emails to an exchange system. Just add the transport and the relay recipient.

    I don’t add a mail domain, only the transport and the relay recipient. But at the relay I forgot the leading @domain.tld. After I have corrected this, only this error message is displayed:
    mx2 postfix/proxymap[17574]: warning: connect to mysql server 127.0.0.1: SSL connection error: SSL_CTX_set_default_verify_paths failed
    mx2 postfix/smtpd[17185]: warning: proxy:mysql:/etc/postfix/mysql-virtual_client.cf lookup error for "mail eopbgr150135.outbound.protection.outlook.com"

    Sounds like you have a bad ssl/certificate setup in mysql.
