Subject in CAPS on palm pre

Hi, I am accessing my zoho account via IMAP on my palm pre, and the subject line of every single email is in capital letters.

Every other account on my pre shows the subject correctly.

Is this a known issue or is there a way to fix this?

Edit: been looking a bit closer and it looks like html content (external images etc.) is being removed from the messages as well. They work fine on other accounts on my pre - is there a mobile device filter or anything that my email is being passed through, and if so is there any way to disable this?
