It's entirely possible. Mine went through a phase a few weeks back where it was throwing out error messages when I tried to open some of my emails, with absolutely no rhyme or reason behind which ones. I'd have people resend the exact same email fifteen seconds later, and that would open just fine, but the original still refused point-blank. Not so much the same as not being able to access mail at all, but still bloody odd.
