We are having a strange issue with some inbound emails - I have isolated them to incoming HTML formatted emails - plain text emails don't seem to be displaying this behaviour.

What is happening is that when some (not all) inbound HTML contain the string "ont" (eg: cONTinue, dONT, pONTificate), these letters are not displayed in the HTML view of the email, but are shown correctly when you tick "Show Plain Text".

Has anyone else seen this, or know how to fix this one???
