Error message on email send and only 1 test email

[MartinaEL]

I am getting the following error on the front end of my Magento 2 website when trying to share Wishlists or send a Contact Form and when I send the SMTP test email. I do receive one of the two test emails though - just not the second;

Warning: stream_socket_enable_crypto(): Peer certificate CN='xxx.au' did not match expected CN=`localhost' in public_html/vendor/magento/zendframework1/library/Zend/Mail/Protocol/Smtp.php on line 206

Magento version #: 2.2.3

Edition (EE, CE, OS, etc): CE

PHP Version: 7

Your SSL cert seems to not be valid.

Take a look at https://stackoverflow.com/questions/30371910/phpmailer-generates-php-warning-stream-socket-enable-crypto-peer-certificate

This is a server config issue and not an extension issue. You are more than welcome to open paid support and we will try to fix it.

Its will showing wrong email address in FROM. It's not use magento system -> configuration mail id for FROM address.
