Strange shortcode [image: Inline image 1]

It appears that Google mail (Gmail) will add a placeholder to the plain text version of your email that looks something like this: [image: Inline image 1]

This will occur for each image¬†inserted “inline” which is the default.This text is actually in the message, Postie is not adding it.The best workaround is to change the “Preferred Text Type” setting to “Html”
