Some email messages from Apple users are blank until I reply and type the
first letter of my reply, then their text appears in the compose window below
my reply.

Hello,

Can you send me one of these faulty emails saved as… (right click… - save as) .eml to [email protected] together with this topic’s URL in subject?

best regards

Hi John,
After I posted this question I decided to purchase eM Client and post a
trouble ticket. Juraj is helping me at present. He was unable to replicate the problem on his computer using one of my emails, so has proposed a Teamviewer session.
Thanks.
Phil
