@kravietz@hal9000 OK I just did some testing too. When sending to an external email address the image tag is used to activate a URL call to the api.Criptext.com server (but no image is downloaded) if these two conditions exist: In your privacy settings you have read receipts set to ON and you send the email unencrypted (a normal email). So I believe @hal9000 is right that this method is used to maintain constant behavior. If however read receipts are turned off or you send the email encrypted..
@kravietz@hal9000 Some more details: The first time you view an email sent unencrypted to an external email address, the image tag URL sends in return code 400, the text "OK". Any further requests for this same image URL and you get an error 429 (too many requests).
