PHP Warning: stream_socket_client(): Failed to enable crypto?

Question

I'm using swiftMailer to send email using SMTP directly.

I get this strange error:

2011/09/23 17:59:01 [error] 489#0: *1032 FastCGI sent in stderr: "PHP Warning:  stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages:

What does it mean? Thanks

The "failure to enable crypto" means that it was unable to secure the connection - check to be sure that you are successfully passing a certificate, and that your passphrase is set correctly.
