Yesterday I received newsletters in HTML & plain text and I only received Avast's signature or only pictures for HTML.
Using Pocomail version 3.0.3 1742 NLD.

The funny thing is that other newsletters, also HTML & plain text, did come through.
My Avast Pro-version is set to 'adding text on incoming and outgoing'.
This all happened since I updated, so maybe there's a bug.
