Do you have a signature html file which you use? Does that signature have any numbers? Suggest you create an email and send it to me so I can check the source code or you create an email, save as a draft, then select the draft email so it shows in Message Pane, click on 'more' and choose 'View source'. Make sure you can see the entire html section. Then post an image of the so the forum can see all the html content. If you prefer to send email to me, then send to: mail at anje dot co dot uk I do not respond to those emails, but will post all comments in this forum. Note, the email address is written phonetically to avoid spam bots that roam public forums.
