Mighty - I am sorry you are getting this. I have blocked my xh's emails (I told him I was going to do this after years of abusive spew). The alternative is to send them direct to a folder and keep them in case you want to protect yourself against harassment at a later date.
It really isn't nice to get this stuff. You are under no obligation to read any of it. Fwiw I think it is guilt, but i could be wrong.
