Description
All email features across my website suddenly stopped working a few months back, this included order confirmations, contact forms, password reset requests, everything. I hadn't updated EE to version 6 because I had concerns with addons not being compatible with the new major version, but when all email across the website broke I decided to run the update. After updating, the issue was still there, so I decided to follow the stack trace and see if there was anything I could fix.
The problem stemmed from the \ee\legacy\libraries\Email.php file, specifically in two lines.
758 $this->newline = in_array($newline, array("\n", "\r\n", "\r")) ? $newline : "\n";
and
1710 $crypto = stream_socket_enable_crypto($this->_smtp_connect, true, STREAM_CRYPTO_METHOD_TLS_CLIENT);
The newline value was not being saved in the CMS, so I set it here in code:
//$this->newline = in_array($newline, array("\n", "\r\n", "\r")) ? $newline : "\n";
$this->newline = "\r\n";
and I changed the stream crypto method to the most recent version:
// $crypto = stream_socket_enable_crypto($this->_smtp_connect, true, STREAM_CRYPTO_METHOD_TLS_CLIENT);
$crypto = stream_socket_enable_crypto($this->_smtp_connect, true, STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT);
These changes got the email class working again.
The problem now is: if I ever run a CMS update, the newer version will replace this fix and the class will stop working again.
