[FavSport:Reading]

I have been using Calibre for quite some time. I have always sent the books to my phone via email and saved them in an ereader app just in case I didn't have my actual ereader with me should I want to do some reading. I have never had a problem doing so. However, we just dumped our home internet service in favor of the, now retired, Verizon Prepaid Unlimited plan. Everything in the house is connected to the jetpack and working flawlessly (in fact, working better than the land line we had before....much faster). However, I cannot seem to get the Calibre emails to work. My email works without an issue for everything else. Any suggestions? I'm baffled.
