After checking this out, it seems that Yahoo's auto-reply puts in an invalid Content-Type: text header (it should be text/plain). I've put in a fix for this, but it's really Yahoo's fault.[/edit]
Can you expand on this one?
I can't duplicate this. You'll have to forward me an email which has this problem.[/edit]
Fixed. The problem is that the email template editor is adding the Date header into the email. I've fixed it in the code, but to fix it temporarily on your side, just edit the .eml files and remove the Date fields.
Yes, you will have to do this each time you save the template, but this shouldn't be a problem since you probably won't be editing it that much.[/edit]
I'll have to look into this one. I don't get html emails that often, but I have seen the odd occurrence where html is in the preview.
Same as (2)[/edit]
I fixed this when you mentioned this in the other thread.
