SMTP username error

[eluser]OES[/eluser]
Hey Gaz

I would check the settings on your editor (Line Endings). As per the error (Failed to authenticate username. Error: 451 Invalid Smtp line - Should end with CRLF)

I would also dicth the idea of using CI's email library with SMTP. Just done a simple email lib for a client due to SMTP not being able to connect to rackspace mail but worked perfect with swiftmail with same settings.

Hope this helps a little.
