ok, I’ve just tried this on my test site with just twentyten and bbppress and it sends with carriage returns, so possible that the email system you are using or indeed the email recipient software is stripping – may be may not be.

otherwise it could be a theme or plugin issue

Themes

As a test switch to a default theme such as twentytwenty, and see if this fixes.

Plugins

If that doesn’t work, also deactivate all plugins apart from bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.

If you cannot do this to your site (say because it is live) then use the ‘troubleshooting’ features of this plugin to let you test without affecting other users

Health Check & Troubleshooting

Then come back
