I have a blog that is hosted by Bluehost. One of my commenters wrote me today to say she is getting offensive emails from my bluehost/comment address - in other words it comes as a reply to a comment on my blog.
I've contacted Bluehost and they can't see any malware on the blog. The only way for someone to have this information is to have hacked into my blog and the comment reply plug in or through my email address.
What do I do?
