A Guide suggested I move this question from the HTC Forum to the Lounge: I'm having an issue with HTC Mail. With one particular message type only. When I try to read it, I see the phone working to download it, then get the message "This mail is still on the server". The only thing different versus other mail (that I can think of) is that it comes from .mil accounts with a digital signature hash. I can read them fine in Thunderbird, and two colleagues who get emails from the same accounts can read them fine on their phones. One has a Droid X, the other has an HTC Windows phone. Both of them are on Verizon, so maybe this could be a Sprint issue versus HTC? I also sent myself an email using my OpenPGP digital signature from my home account last night as a test, and it does the same thing. To be clear, these are not encrypted emails, they are simply using the public signature hashes used for non-repudiation. Anyway, if anyone else has run into this or has suggestions, it would be most appreciated.
