Yes, somehow my MBP is blocking them from being delivered from the ISP. It has to be the Junk Mail Filtering. "Trust Junk Mail Headers in Messages"? Everywhere else says to put junk mail in the trash and color it grey. So, maybe now that I have specified those messages in EarthLink webmail as spam, EarthLink may catch them before they reach the iPad. What I really don't like about these spams I described is those weird domains ask for port access (Little Snitch). Probably just to download their self-hosted images. It's probably OK in the case of the iPad because images on those emails don't load anyway.
