I only read text-only email, anything else gets deleted - not my problem if I never received it.
You wouldn't be a Pegasus Client, client by any chance? I used that email client for many years.
No, before I had a computer, (pre 1984), I used pine on a Linux/BSD server I had access to; followed by Thor on the Amiga; then straight to Thunderbird on the PC.
I just hate HTML email, there is no logical reason for it to exist.
