Server Error - Emailing Users

Is there anything in the Server Error Logs?

Do you have any email sending limits? Shared hosts for example usually only allow a few hundred per hour (not that it should cause this error).
Server error logs show: fwrite(): SSL operation failed with code 1. OpenSSL Error messages: error:140D00CF:SSL routines:func(208):reason(207) library/Zend/Mail/Protocol/Abstract.php:324 Today at 3:10 AM Details

My host is a dedicated box, it's using smtp to google (commercial). The number of messages it was going to send was 13,000.

Something went wrong verifying the certificate from Google it looks like (SSL_F_SSL_VERIFY_CERT_CHAIN). Given that it worked for a few, I'm not sure why it would break after a little while. A low-level error like that is definitely something we don't have control over.
