One reason I don't like using my iPad for email is that I can't find a way to move a junk message without its message body being automatically displayed when selected. While viewing a mailbox, tapping Edit then selecting a message will show the message body.
My concern is that HTML code in the message could let a spammer know that the message sent to me was viewed, confirming validity of my email address. Is this concern valid? What can I do in Apple's Mail app on iPad to move junk messages without viewing the message body?
I store my junk messages in an IMAP folder, and use
grep to see which email addresses are being targeted.
