Mail Download & display issues

I have a couple of issues,

  1. I get emails that have no subject or body just the source code!
  2. Some email just turn into a row of hex charecters!

I can check the mail online and the mails to issue 1 are complete, but those affected by issue 2 are the same.
Why, are they linked?
Thanks in advance
Stu

Hello,

Please send me (pukan@emclient.com) an .eml export (Menu-File-Export) of some broken emails. Preferably where I can see issue 1, 2 and even both happening.
