Thanks for the quick reply. The extra newlines are within the content block. In fact, since I'm composing this mail with RoundCube, you'll see the extra ^Ms (or =0D's while viewing source in a browser) at the end of every line.
OK, then forget about the header_delimiter config parameter.
You are correct, I'm not actually specifying an SMTP server.
Then you can try to set the 'smtp_server' config parameter to let RoundCube talk directly to the SMTP server instead of using mail(). Not sure if it helps but at least we can localize the problem.
