Just curious, but is there any way to get this plugin to just send what it gets and not mess with the formatting? SMTP plugins seem to work fine with whatever is thrown at them, but this one messages with the formatting. Not easy to correct if you have pieces sending out plain text and others sending out HTML. The only way to correct this would be to modify all the plugins - or use a SMTP plugin. The easiest choice is to just use an SMTP plugin.
