I am using 6.5.4 Pro and have been for many years with much satisfaction. However recently in the last 10 days I have been increasingly receiving emails with an apparent blank body to the email. I can see the content if I request a header view, or open in webmail.
I have seen this reported elsewhere, where the advice is to upgrade. What is the cause of the recent behaviour? What is involved in an upgrade? Is there a cost to this?
Many thanks
