Email library produces weird error while sending mails

I'm having the same problem. I had it working great and on Friday it started throwing the following error:

"A PHP Error was encountered
Severity: Notice
Message: fwrite() [function.fwrite]: send of 3293 bytes failed with errno=32 Broken pipe
Filename: libraries/Email.php
Line Number: 1816"

I've tried all the suggestions from above. I even took the time to 60 instead of 30. 

BlueHost says all my configurations look good on their end. They even did a PHP Mail script from the website to make sure it was working and it is. 

Any suggestions?
